How many emails can you really send with GMass and Gmail?

GMass Flying EmailsGmail officially claims that with a regular Gmail account you can send 500 emails/day and with a Google Apps account you can send 2,000 emails/day. In fact, I’ve even claimed that with GMass, if you’re a Google Apps 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 Google Apps 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 brand 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 brand new Google Apps account, where the organization itself is new to Google Apps, also has very limited sending ability.
  • A brand new Google Apps 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. Here are step by step instructions.

Special Privilege for G Suite Users

If you have a G Suite (aka Google Apps) 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 us. 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 really 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.

    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!

      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?

    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,

    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.

    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.

    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,

    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!

    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.

    Dear Sir/ Madam ,
    I request you to please support me to successfully send the mail because every time your GMass system prove failure . Thanks Nishant choudhary

    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.
