How many emails can you really send with GMass and Gmail? [Updated 2018]

GMass Flying EmailsGmail officially claims that with a regular Gmail account you can send 500 emails/day and with a G Suite account you can send 2,000 emails/day. In fact, I’ve even claimed that with GMass, if you’re a G Suite user, you can send a 10,000 recipient campaign, where GMass will evenly distribute the campaign at 2,000 emails/day for 5 consecutive days.

So if you’re using GMass, you should be able to send 60,000 emails/month (2,000/day x 30 days in a month) from a single G Suite account, right? As it turns out, that usually isn’t the case.

In working with over 40,000 accounts in the last year, we’ve noticed that Google often throttles the number of emails a particular account can send based on a variety of factors, including:

  • How old the particular Gmail or Google apps account is (the older, the better)
  • How many conversations exist in the account (may existing conversations are better)
  • Whether the account has sent mass emails before (if it has, then you’re better off)
  • The content of the mass emails (non-spammy content)
  • The bounce rate of the overall account (the lower the better)

We don’t have exact rules on how Google decides how many emails an account can send at a particular time, but here’s what we’ve observed:

  • A new Gmail account (ending in or with no history has very limited sending ability. Sometimes you are limited to 10 emails right when the account is created.
  • A new G Suite account, where the organization itself is new to Google Apps, also has very limited sending ability.
  • A new G Suite account, where the organization has a history with Google Apps, can send near the 2,000 emails/day limit almost right away

So what happens when you try to send, and Google decides you are over limit?

Using GMass, you’ll notice that Gmail will start bouncing the emails and the bounce notification will look like this:

This is the Bounce you’ll see if GMass sends an email when your account is over limit.
If you are in the Gmail interface, and you try to send a regular email with the regular blue Send button, you’ll be stopped with a popup that looks like this:
This is the error you’ll get if you try to send an email with the regular Gmail Send button when your account is over limit.

What does GMass do when it detects that your account is over limit?

GMass looks for bounce notifications like the one shown above to determine if your account is over limit. In fact, while it’s sending your campaign, it’s also simultaneously monitoring for these bounces. If the bounces start to appear, and you are technically under the 500 or 2,000 limit, then GMass pauses your campaign for an hour and tries to continue sending later.

Does GMass re-send the emails that have already bounced?

No, GMass won’t automatically resend the emails that have bounced with an over-limit message, but you can easily resend these emails after you determine that your account has more sending ability.

Special Privilege for G Suite Users

If you have a G Suite account, and you’ve reached your limit and are unable to send emails, you have the option of having your G Suite administrator “reset” your account. This is done through the G Suite Admin console. By resetting your account, your daily quota is immediately reset. This option, however, can only be used 5 times per year per account, so use this sparingly…only in situations where you’ve hit your limit and you absolutely need to send more email, whether it’s through GMass or person-to-person email with the regular Send button.

Does subscribing to a paid GMass account improve my ability to send?

No, it does not. Whether you have a free or a paid GMass account, your overall sending limit per day is the same and is determined by Gmail, not by GMass. A free GMass account limits you to 50 emails at a time, but only Gmail imposes restrictions on total emails sent per day. We’ve had users express surprise that they subscribed to GMass, yet still couldn’t send as many emails as the Gmail published limits, so it’s important to know that GMass has no ability to control how many total emails you can send per day.

So how many emails can I natively send with GMass and Gmail?

If you have a Gmail account with an excellent reputation, you’ll usually get your 500 email limit for the first 24 hours but only a subset of that for the second 24-hour period. Meaning, if you send 750 emails, where GMass sends the first batch of 450 now (so you have a buffer of 50), and the remaining 300 24 hours later, that usually works. Avoid sending 900 though, because then you would need your full sending ability during the second 24-hour period.

If you have a Google Apps account with an excellent reputation, you’ll usually get the full 2,000 email limit for the first 24 hours but only a subset of that for the second 24-hour period. So, you can probably send 3,500 emails, where 1,950 go out the first day, and the remaining go out on the second day, but if you were to send 4,000 emails, you might get some bounces on the second day.

Breaking Gmail’s sending limits

Using a new capability introduced in October 2017, you can now “break” Gmail’s sending limits and send an unlimited number of emails through your Gmail account. It works by connecting your account to a third-party SMTP service like Sendgrid. You still launch your email outreach campaigns from Gmail, just like normal, but your emails bypass Google’s servers and are sent via the third-party SMTP service instead.

    Hi there,

    Although we do check our blog comments, the best ways to get support from the GMass team are here:

    To answer your question, if you have a free account, there is a limit of 50 emails per day sent through GMass. Once subscribed, we do not limit sending in any way, and your maximum sending is determined by your Gmail account. You're right that a regular Gmail account should have a limit of 500 emails/day.

    If you'd like us to look further into what's going on, feel free to email and open a ticket with our help team!

    • Maya Quijada

      Free accounts are limited to 50 emails sent through GMass per 24 hours. Subscribed accounts do not have limits imposed on them by GMass.

    We have a regular free Google Apps account. I tried to send out over 1,000 emails yesterday afternoon. i did receive a notice “your message did not reach some or all of the intended recipients. . . Daily user sending quota exceeded. . .” will I need to resend the emails that would not send yesterday or will they send out automatically after 24 hours from the last send?

  3. Farzad Hejazi

    I am using university email and I tried to send daily 2000 emails and after one week I am not able to send any group email since my email is blocked. If I use the GMass , can I send again daily 2000 emails or since my email is blocked it will not function?

    • Maya Quijada

      If your email account has been blocked by Google, we cannot recover the account on your behalf. Contact your domain administrator to recover the account.

      If the account is recovered, you will be able to use GMass, but we recommend sending at a lower number until you’re sure of the sending limit for your account.

    I am using Google Apps, I am trying to send camping with Gmass, but I am only able to send per day 400 Mail,

    Could you pls inform me how I can increase send mail?


  5. Leonard Willis

    I paid for Gmass and I won’t be renewing for next month,because you decides who gets the most e-mails sent out and thats BS! I know when I have been conned.


    I am using Business Gmail . When I started to send emails thru Gmass, first day I could send 250 and then after 2 days the limit became just 50. I am not sure if Gmass really works well as a Bulk email sender. I like Gmass the way it works but if I can only send 50-60 emails in a day then it absolutely doesn’t server the purpose. Note that I have a paid Gmass account and I have less than 2-3 % bounce (because of incorrect emails). I think the claim of Gmass in this blog is not true.

    I have a paid account, since August 7 2017. and today we are August 22, I am trying to send email, now You are asking me to upgrade , why?
    Please rectify

  8. julio Cesar Vieira

    Isso é propaganda enganosa, a gente paga por um plano ilimitado e não consegue enviar uma lista de 500 emais.
    Sempre tem um problema, que bosta de plano.
    Não vou renovar nunca mais.
    vou procurar outro navegador.

  9. Omar Gervacio

    Emails been bouncing due to being over the limit, I had stopped the campaign a day ago but for some reason it still sending out emails and still I’ve been receiving the bounce message from google; how do I stop it completely?

  10. Andrew

    Just purchased Gmass a few days ago. I had sent 1-2 emails from this account in the 48 hours prior.

    I tried to send out a campaign with about 400 emails. Yet, upon reaching email #170, Google says my account limit has been exceeded. Then, for the every 3-4 hours Gmass attempts to send the rest, Gmail only lets 10 emails go out until the limit has been reached again.

    So for every few hours after that, I get messages like:
    GMass has sent 10 of 228 emails – your account’s limit has been exceeded
    GMass has sent 10 of 218 emails – your account’s limit has been exceeded
    GMass has sent 10 of 208 emails – your account’s limit has been exceeded

    This blog post clearly states I should be able to send out 500 per day when using Gmass –

    Can you please look into this? Why is my limit capped around 170 despite sending no emails prior? Paying for GMass is useless if this is the case. Thanks,

  11. daniel

    I paid for gmass + gsuite account and I cant send more than 50 emails without gmass sending me an error saying that they have detected that gmail has started to bounce my emails (verified email subscribers only) because “I’ve exceeded their limits”…. how does this make any sense?? this page clearly states that I should be able to send out 200+ emails/day without any issues after upgrading (gmass states 2000+). I’m starting to doubt that gmass can send anything above 50 messages paid or not. PLEASE HELP!

  12. Balal

    Hi, I tried to send a message today 3 times and received these emails:

    Message 1 (sent at 03:24 pm GMT+2)
    – Email that the message is not sent at 03:24 pm GMT+2
    – Email that the same message is opened by recipient at 03:27 pm GMT+2

    Message 2 (sent at 06:22 pm GMT+2)
    – Email that the message is not sent at 06:22 pm GMT+2
    – Email that the message is opened by recipient at 06:40 pm GMT+2

    Message 3 (sent at 09:04 pm GMT+2)
    – Email that the message is not sent at 09:04 pm GMT+2
    – Email that the message is opened by recipient at 09:05 pm GMT+2

    It is confusing that I receive 2 emails saying the thing and its opposite, so I want to know are these emails sent or not?

    Another question: I receive emails saying that I have reached my sending Limit and I only sent 80-85 emails and when I click on “Show Usage” from GMass Settings button. I read that I have remaining 410 emails today (again the thing and its opposite). Shouldn’t my limit be 500 emails/day as I have a standard subscription.

    I tried to send this complaint to and recieved the same message that I reached the sending limit. Please reply as soon as possible.

    My boss, an Athletic Director at our school, is unable to send mass emails to all of our coaches at once. The district added gmass to his account. It has not helped at all. He is getting very frustrated at not being able to send important emails to the whole group. He has to send the email to me and I forward it to all of them. I am able to send to more than 20 emails at a time on my email. He is new to our district this year and has been having this issue since being given his school gmail address. Our tech people in the district can’t seem to help him solve this issue and I have tried to find any solution in your links. His gmail account through our school district is

      Hi Ayobami,

      You can open a compose tab and click on the little arrow pointing up next to the GMass button. At the bottom of the GMass menu, you will see one of the following: Free, Premium, Standard.

      This indicates the type of your subscription connected to that particular email address.

  15. DJ Paris

    FYI, my brand new Google Apps account started bouncing after about 100 emails on day one (same day I bought Google Apps).

    On day two, after 50 emails it started bouncing.

    I guess the takeaway is that it will take some time before you can get to 2-5k a day on Google Apps accounts if they’re new.

    Hope this helps new users.

    • Marvin Quinsaat

      Hi DJ,

      Yes, it would take some time for email accounts to build up a reputation. Since it’s Google that decides the sending limits, we advise our users to send smaller campaigns to start and slowly increasing that number over time.

  16. Mickey Shelby

    This is stupid on googles end…you should have a limit counter for each email you insert,how i suppose to know how many emails i can send after i before i get penalized? yall need to do better….

    • Marvin Quinsaat

      Hi Mickey,

      Unfortunately, it is Google who imposes the limits to lower sending capacity until the account establishes its credibility. This is a measure to prevent scammers and spammers from opening accounts and sending at full capacity.



  18. mark

    Schedule ID 1414385 and Campaign ID 2288830. This campaign has sent 1 emails so far. It has been processed 1 time(s). It will send next at 4/26/2018 9:40:11 PM GMT time, which is in 24 hours.

  19. SU

    Tired free trial version but 40 emails not sent and bounce back? I really want to subscribe premium package but this free version doesn’t work perfectly like I think. Can you give me any answers?


    hello I paid for unlimited plan, if there is limitation, then you’re fooling me
    I want my money back, I paid today, by paypal
    waiting for his return as soon as possible
    there is a limitation that is not dictated when you make the payment, this is deceit, do not do this to those who are working hard.

  21. wrkilu

    I purchased “standard” package and still I have limit for 50 emails/day – disaster. Gmass cheating people!!

  22. Jonathan Moller

    This is ridiculous, I’m paying $8.95/month to GMASS, and I have NOT passed my daily 500 emails/day limit with GMAIL — 48 hours ago I “sent” an email via GMASS to 458 addresses, and iGMASS still hasn’t sent them all, after 12 times sending only small batches each time over 48 hours, and still not finished!!! I can’t send more until Gmass finishes! I’ll cancel GMASS, after all I can send up to 500 in one day just with my free GMAIL!!! Here’s the latest Gmass message regarding this email I “sent” 48 hours ago:

    “Schedule ID 1576217 and Campaign ID 2509573. This campaign has sent 150 emails so far. It has been processed 12 time(s). It will send next at 6/17/2018 12:03:54 AM GMT time, which is in 21 minutes.”

    • Marvin Quinsaat

      Hi Jonathan,

      Google limit accounts to lower sending capacity until the account establishes its credibility. This is a measure to prevent scammers and spammers from opening accounts and sending at full capacity.

      There’s some more information about these limits and factors here:

      GMass keeps sending until the campaign is finished based on those limits imposed by Google.

      As for the limits, we have also placed an explanation to why your campaign was paused.

      “This send has been paused because GMass detected that Gmail is bouncing your emails because you exceeded their limits. GMass will attempt to continue sending at the time noted above. You may be below your Gmail account’s official sending limits, even though Gmail has started bouncing your emails.”

  24. Larry

    I have google app account, but it seems that my email limit is down to 10 emails/day.
    Can someone help me? Thanks.

    • Marvin Quinsaat

      Hi Larry,

      Our subscriptions do not have usage limits. Although Google Apps accounts are officially limited to 2,000 emails per day, we have noticed over time that there are other factors that affect the send limits for an account. Age is a huge factor in this, as Google limit accounts to lower sending capacity until the account establishes its credibility. This is a measure to prevent scammers and spammers from opening accounts and sending at full capacity.

      There’s some more information about these limits and factors here:

    • Marvin Quinsaat

      Hi Soumya,

      We mention that an account’s age is a factor to what sending limits Google decides to impose on each account. This is a step taken by Google to ensure that spammers can’t keep creating new Gmail accounts and send at full capacity every time.

    • Marvin Quinsaat

      Hi Duy,

      Emails being marked as spam is due to a number of factors which includes but not limited to your domain, your content, and your email address’ reputation. This is all dependent on your recipients’ email provider’spam filters. We have our support team that you could have contacted to assist you in pinpointing what is causing your emails to be sent in spam and what steps you can take to resolve it.

      Paying for a year means that you’re committing to a year and have already tried out our services and saw that it fit your needs. Signing up for a year is optional, we have a monthly subscription as well as a free version that would allow you to send up to 50 emails per rolling 24 hours as a test bed to see how GMass would fit your needs.

    • Marvin Quinsaat

      Hi Alex,

      I’ve checked your emails and found that you have a subscription on your alexjarbousmc@ email account but not on GMass subscriptions are per Gmail or G Suite account, and GMass doesn’t care what alias addresses are connected to a single account. So if you have all of your aliases on the various domains set up in a single Gmail account, and that single Gmail account is subscribed to GMass, then you are able to send from all of those different alias addresses with a single GMass subscription.

      If, however, those aliases are spread across multiple Gmail accounts, then you would need a subscription for each of those Gmail accounts.

  25. Robert Negru

    I have a paid account since September 11 (, but since last night i can’t send any email.
    When i’m going to GMass > Schedule > Show usage the message is: “You’ve sent 150-160 total emails over the last 24 hours, and 154 with GMass. This means you can send about 340 emails right now, if your account has a good reputation with Gmail. See this article about sending limits.”
    But i can’t send any mail, i receive an email back with “You have reached a limit for sending mail. Your message was not sent.” no matter if i send with Send button or GMass button, even to 1 person.
    Also i set account few days ago, but 2 days ago they suspended my smtp account and is not working anymore if i want to send with GMass via smtp. So i simply want you to remove my smtp account from GMass.

This is a measure to prevent scammers and spammers from opening accounts and sending at full capacity. 

      To remove your SMTP account from GMass, create a new compose with the TO field set as and in the subject field put the word CLEAR, then click on the GMass button.

  26. Silas

    If i load 5,000 emails, will it send 500 daily and how do i know its sent?

  28. Abdul Wahid

    Does Gmass include its own branding in the footer of the email? Also, if I have G Suite and wanted to use Gmass (free) what is the limit?

    • Marvin Quinsaat

      Hi Abdul,

      Minimal subscription plans have the link to GMass at the footer. Standard and Premium subscriptions do not have those footer links.

      For the free version of GMass, the limit is capped at 50 emails per rolling 24 hours regardless if you’re using a Gmail or G Suite account.

  29. Laura

    I just downloaded Gmass, I am the President of PTA from a school. I have an email group set with 221 emails, that i need to send at once. I was doing it in bcc, how do i do it with Gmass?

    • Marvin Quinsaat

      Hi Laura,

      You would just need to add those 221 email addresses in the TO field, compose your email and click on the red GMass button. An easier way to manage your list would be to create a Google sheet to connect with GMass, this will give you more options such as personalization. When you click on the GMass button, GMass will send each of your recipients an individual email. Please see for more information.

  30. Nikos

    I am trying to send an email to some colleagues, around 40 addresses.
    I haven’t used Gmass for 24 hours, and it is confirmed by clicking on the Show Usage button that I have sent 0 emails.

    It doesn’t allow me to send the email thought, saying that the limit is 50 and I need to upgrade to a paid plan. I have only used the regular Gmail send function but not Gmass

    How exactly is the limit calculated?
    Is it 50 emails with Gmass, or is it calculating the total usage of the account even though the Gmass service hasn’t been used?

  31. Maria Gamero

    Hello, I have one question. What do you consider a “good reputation” ? I have a gmail account for the last 10 years, and I need to send 3000 emails this week. I download the GMASS application, but not sure if it will work. Thanks!

  32. mike okereke

    • Marvin Quinsaat

      Hi Mike,

      GMass will continue to send your campaign based on your Gmail account’s sending limit each day until all emails have been sent.

  33. Shawn

    So Gmass is now senidng 10 emails every 4 hours. My big mailing was on Friday night. Shouldn’t I be able to do another 450 emails rather than continuing to do 10 emails every 4 hours. It will take much, much too long to complete:)

    How many emails can you really send with GMass and Gmail? [Updated 2018]


  35. Summer

    How are 24 hours calculated? I have sent some emails yesterday and today I want to set a schedule for evening but could not.

    • Marvin Quinsaat

      Hi Summer,

      The sending limit for free accounts is based on a rolling 24 hour period. If for example you sent a campaign to 30 addresses at 9AM today, you can send a total of 20 more emails from 9:01AM to 8:59AM the following day.
