You can now send 10,000 emails with GMass and Gmail [Updated 2018]

GMass Flying EmailsThis has been the hardest feature we’ve developed to date, but we pulled it off just in time for Christmas. It’s time to reload Gmail (just hit the Refresh button in Chrome), because you can now send mass email campaigns with 10,000 emails with GMass, and GMass will distribute the emails over multiple days automatically, based on your Gmail account’s sending limits.

If you have a regular Gmail account, you can send up to 500 emails per rolling 24 hours. If you have a G Suite (formerly known as Google Apps) account, you can send up to 2,000 emails per rolling 24 hours.

For example, if you have a Google Sheets spreadsheet with 8,000 addresses, and you’re sending from a G Suite account, when you hit the GMass button, 2,000 emails will send immediately, another 2,000 will send 24 hours from then, another 2,000 48 hours from then, and the final 2,000 72 hours from then.

GMass itself now has over 150,000 users, meaning I need to use this feature myself whenever I send an announcement to my users.

This feature is only useful if your emails are NOT time-sensitive. Most GMass announcements, like this one you’re reading right now, are not time-sensitive, so I’m able to use this new capability of GMass to send GMass announcements. Rather meta, I believe!

GMass will automatically send 500 emails/day or 2,000 emails/day if your email campaign has more than 500 or 2,000 recipients, respectively. You can also control, however, how many go out per day with the new Spread out setting under the GMass Settings arrow. If left blank, GMass will use 500 (regular Gmail) or 2,000 (G Suite) automatically, but you can override this by setting your own value.

Other Useful Information

1. How the timing works

Because Gmail tracks total emails sent on a rolling 24 hour basis, each subsequent batch of emails will be sent exactly 24 hours after the last email from the previous batch is sent. For example, if you send 8,000 emails on Wednesday at 2:00 PM, then the first 2,000 will be sent right away. If they finish sending at 2:15 PM, then the next batch of 2,000 will be sent at 2:15 PM on Thursday.

2. For large sends, you will notice a new alias address format in the To field of the Compose window.

If you connect to a Google Sheets spreadsheet with more than 2,000 addresses, then instead of populating the To field with all 2,000 addresses, you’ll see an address that looks like:

This address represents all 2,000 recipient email addresses. When you hit the GMass button, the sending to the first batch of 8,000 addresses will begin. The reason we use an alias address instead of stuffing all 8,000 addresses in the To field is because the Gmail Compose window no longer functions with 4,000 or more addresses in the To field. We also do this because even loading a few thousand addresses in the To field takes a long time and we don’t like making you, the user, wait.

3. You may want to use a “Spread out” factor of slightly less than 500 or 2000.

If you send regular one-to-one correspondence from your regular Gmail account, you may want to set your mail merge to send at say, 450 emails/day rather than 500 emails/day, so you have a buffer of 50 emails/day for your regular email correspondence. Similarly, if you’re a G Suite user, you may want to set this to 1,900 instead of letting the system default to 2,000. Sometimes, Gmail doesn’t give you your account’s full sending ability, so this needs to be adjusted down in these cases.

4. This feature keeps track of all sending activity in your account.

If you’re a G Suite user and you’re sending a single mass email 8,000 people, then your email will send at 2,000/day over 4 days. If you don’t need to send any other mass emails for those 4 days, then this will work perfectly. If you do need to send other mass emails over those 4 days, GMass will count how many other emails have been sent from your account in the last 24 hours and adjust your campaign sending speed accordingly. After any batch of emails is sent, you receive an emailed report showing you how many emails were sent, when the next batch will send, and an explanation for any forced throttling put in place for you to prevent you from reaching your Gmail limits.

5. You can bypass Gmail’s servers altogether and send unlimited emails

Launched in October of 2017, this new capability lets you send an unlimited number of emails from your Gmail account. Need to send a campaign to 250,000 people? Just connect your GMass account to a third-party service like Sendgrid, and you can send as many emails as you want, right from the familiar Gmail interface.

    In order to use the campaign, do you have to be logged on 24hrs, or will it really automatically send them each day without you being logged in? Thanks!

  2. e.t.

    I spotted a trouble: the GMass Report periodically report that by 4 different email addresses (locate in different places in the world) is clicked a link in the message, and this many time a day, and always the same 4 and at the same time!
    The report – along few days – list hundred time the same thing.

  3. puchitzel


    I think Gmass is exactly the tool i'm looking for (great app !!!), but before I start using it I just want to know precisely a couple of things.

    I intend to send around 1000 mails "divided" on chunks of approximately 100 / day.
    1. After I set all the parameters do I need to log every day on the google mail account in order to help "the miracle happen". I mean if I dont "see" the account daily, the daily job will be delayed to the next day after i log in?
    2. How do I verify that the 100 mails have been sent on a day. Do I have to look on "Sent mails"? Are they sent at the same hour or spread in 24 hours?

    Thank you.

    Best regards,

  4. Ajay Goel

    Yes. If you go to the "GMass Scheduled" label and open up the email campaign that is scheduled, GMass will tell you the status of that campaign (how many emails have sent, how many remain to be sent, how many times the campaign has been processed). You can also make changes to the schedule and the campaign from here as well. Just click the GMass button after making changes.

  5. Ajay Goel

    No offense taken. Generally if you're not sending spam, and people aren't reporting your email as spam, there is very little chance Google will suspend your account.

  6. Ajay Goel

    1. You do NOT need to log in every day once you have scheduled your email campaign. The emails will send per the daily schedule regardless of whether you're logged in or not.

    2. You can look in your Sent Mail folder, or you can find the campaign in "GMass Scheduled", click on it, and the yellow status bar above will tell you the sending status of the campaign.

    • Arun

      Hi Ajay

      Is there a way to introduce a delay between emails so that spam filters do not flag emails when sent to multiple contacts in an organization. Usually a 10 sec delay is considered okay.

      Please advice.

  7. puchitzel

    thank you very much for your answer.
    like i said it exactly what i need.

    please tell me if the schedule can be made on intervals smaller than one day… I mean 10 / mail hourly. I'm asking that because some spam filter "cut" the mails directed to a specific server and looks identical…

    (if the mails are sent on ONE BY ONE or in small groups the question has no sense)

    Thank you

  8. NicholeK

    I have a Google Apps email account, but when I sent an email to 718 recipients yesterday using GMass, 218 bounced back. I have nothing under the "GMass Scheduled" label. I also don't know which 218 failed without opening up each email that bounced back, which leaves me in a spot where I have to resend to everyone again if the 218 aren't scheduled.

    Is it safe to assume that since the "Scheduled" label is empty, it's not going to resend? And how do I avoid this in the future?

  9. Anonymous


    I set up Gmass to create 380 Drafts, because of the limits it only created 160 Drafts that i sent out. I received a message the I would have to wait for another 24 hours which is not a problem.

    My question is will Gmass automatically create the remaining drafts after 24 hours without my intervention? Thanks in advance

  10. Matt

    That would be great if GMASS could spread all email sent over the entire day.

    So 1 email is sent and after 'x' seconds/minutes, another email is sent… that way it looks more natural and will surely help the deliverability of the campaign

  11. Unknown

    I think this is a tremendously smart feature… new update as of May 19th, 2016 5:22am, Google started bouncing e-mails around ~80 emails per blast… perhaps we could have a feature that would enable us to send out one email per minute? Or maybe, 10 emails in a minute? Just a suggestion — otherwise fantastic tool so far it's working like a charm with facebook emails…

  12. Ajay Goel

    I am considering a mechanism like that, although I don't know if that will help much. You still won't be able to exceed your account's quota, even if you slow down the rate of email transmission. The deliverability with GMass should already be really high, because you're sending from Gmail's servers.

  13. Andrew Maynes

    I received a lot of unable to send from a small list of contacts, the gmail account is setup using an alias could this be an issue as the smtp is that of the domain and not googles? plus I noticed a reference to ?

  14. Ajay Goel

    Andrew — please email me at with the Gmail account you're using and the Campaign ID, if you have it. Then I can look up exactly what is happening with your account.

    We do use Sendgrid to send certain notifications to our users, like when a campaign is done sending. All sending of your actual campaigns is done through your Gmail account though, not through Sendgrid.

  15. Unknown

    My account is doing the same thing and I haven't even sent close to the gmail limit. I only set it up for 350 emails just so it doesn't bounce. Now every time I try to send a gmass it bounces back and locks me out.

  16. mazharoddin's blog

    Hi Ajay,

    Its really nice tool, but my account got suspended after sending around 1000 mails, I am not very sure the reason, but may be its due to high bounce rate.
    Can you please let me know how to stop a campaign after it's been scheduled, I would like to stop the campaign so that google won't suspend my account again.

    Also if possible please provide some mechanism to change the e-mail frequency per day so that it don't look like automated mail service. Thanks.

    But definitely its a nice tool.

  17. Maulik Shah

    I have added just 80 email address in mail list but GMass button not able to send that mail. If I select just 15 then GMass can work properly.

    So can you please aware my why its done?

  18. Yash

    I have a google apps account with a limit of 2,000 emails per day. If I have a list of 50,000+ email addresses, will it take 25 days to get sent? or will the emails stop getting sent at 10,000?

  19. Unknown

    I've recently subscribed to the GMASS service as I thought it would be a good solution for my relatively small outreach (just over 1400 emails) to which I send emails to once or twice a month. Initial test on 10 people worked great. However, my first attempt at sending en mass to the 1400+ 3 weeks ago was disappointing. Not sure if I'm doing something wrong: In the To: field I put the gmail contact group that has the 1400, names and followed the instructions to set up and send the email. After 5 days I checked the campaign which showed that emails were only sent to 500 emails. If I understand correctly how GMASS works, all 1400+ emails should have been sent automatically within 3 days. Would appreciate it if someone can get back to me, otherwise I'll have to cancel my subscription.

  20. Diego Oliveira Sanchez

    How does this feature work along automatic follow ups?

    E.g. I want to contact 1,000 people, sending 100 emails per day. I want to also add 3 follow ups per person (one each 3 days). So in total, that would be 4,000 emails.

    If I set the limit of spreading out 100 per day, I am thinking:
    a) It will email 100 NEW people per day. Then, on day 4, it will send 100 emails to a new batch PLUS 100 follow up emails to the first batch. On day 10, this will mean 400 emails (100 to batch 10, 100 follow up to batch 7, 100 follow up to batch 4, and 100 final follow up to batch 1). Is this how it works since the feature is blind of other campaigns?
    b) Will this feature cut down follow up emails to ensure the limit of 100 is kept every day?
    c) Something else?

    It would be great to clarify which of the 3 above is the correct answer. I am using a brand new Google Apps account, and I want to make sure I don’t go over the limits.


    • Maya Quijada

      Gmail officially limits Gmail accounts to 500 emails per 24 hours, and Google Apps accounts to 2,000. You can use GMass to send to 1900 recipients, and the message will go as an individual email to each recipient. It will not send as a BCC but as an individual email – so none of your contacts will be exposed to each other.

  21. Lokesh

    If I send an email to 100 people through GMASS, I dont want to see 100 emails in my sent folder. To clean the sent folder every day takes time. Is there any way to not to put all these 100 mails in sent folder as the content for all the emails is same therefore just one email in sent folder is fine.
    Thank You,

  22. Amir

    Gmass can i have your contact details?

    I have opportunity and if you can help me to do that we can work together for long time.

    I want to send bulk emails using gmail (G suite) and i thought you can help me out to do this.

    I want to talk to you in detail for you. Can you give me your skype?

    I sent 400 Emails and almost all the mails bounce back with the message that you have crossed the daily sending limit .. How come this possible as I have paid for 400 email per day ( 24 hours ) Please suggest !!

  24. Elva Hernandez

    how will i come to know the quota? like if i send now some 48emails and nxt few minutes i need to send more emails how will i come to know the limit remaining??

  25. Sarah


    I dont understand why I cant made the scheduling work. I have connected a G Sheet with 4000 emails, set a chedule to send 490/day. The first day it did send 490, but after that it sends 50-100/day.
    I have “Repeat – daily on new sheets addresses”
    Send 490 emails/day.
    What else I need to set up?

    • Sarah

      It says “This campaign has sent 570 emails so far. It has been processed 7 time(s). It will send next at 12/3/2017 11:59:01 AM GMT time, which is in 3 hours. This campaign will send daily based on new addresses”
      So 490 of these 570 are from the first send, on day 1, after that for 2 days it has send 80 emails with 7 time process?? Why? It should send 490 each day for 8 days (the email sheet has 4000 emails)
      BTW I do not have the “Spread emails” option that is in your PDF begginners guide. I guess the guide is outdated, but thats why I want to do – spread the sending of the 4000 emails with 490/day.
      How do I do that?

  26. Angie wond

    hi, i just want to know sending 50 emails per day it is the free feature of Gmass (i can use all the time right?). if i subscribe how much i can send daily?

    • Maya Quijada

      A free GMass account can send up to 50 emails per rolling 24 hours. There is no designated period of time, so yes, you can use it all the time if you’re staying under the 50 email limit.

      For subscribed accounts, the sending limit is something that is enforced by Gmail, not by GMass. According to Google, regular Gmail accounts are officially limited to 500 emails/day, while G Suite accounts are limited to 2,000. But other factors like the age of the account, content of the Campaign, or reputation of the domain can affect your sending limit.

      There’s some more information about these limits here:

      However, you can configure your account with an external SMTP server if you’d like to send unlimited emails without Gmail-imposed sending limits. See:

  27. Cass

    Can I send 3 separate emails with 2000 recipients per email in one day? I would send a total of 6000 emails that day, with 200 emails containing one message, another 2000 emails containing another message, and another 2000 emails containing another message. All 6000 emails, however, must be sent on the same day, and preferably around the same time that day. Is that possible? How much would I have to pay for this feature?

  29. Kaja

    Hi, I have a question. 🙂
    I have paid gmass plan. I added my domain email adress to gmail, to send and recive mails directl in it.
    I tried to send mass mail (300 recepients) with my domain adress and it worked.

    But now I’m wondering, how to send unlimited mails with my own domain? Do I need to set up external smtp (like sendgrid, which I added to my gmail adress), or can I just ask my server provider to allow me to send more emails and will work?
    Will it also work now, that I added sendgrid to gmail and send with my domain adress?

    I hope you can help! 🙂 It is really the best app ever.

    • Marvin Quinsaat

      Hi Esteban,

      It would be dependent on the GMail limits for your account. Our subscriptions do not have usage limits. Although Google Apps accounts are officially limited to 2,000 emails per day while Gmail accounts to 500 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.

      Hi Jinal,

      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: ( )

      We recommend that in situations like yours, users ‘warm up’ their account by sending smaller campaigns over time to establish a reputation for the account and the domain. We don’t want your behaviors to flag Google’s spam detectors and cause bigger problems for you down the line. The more you use your G Suite to send and receive, the more it garners reputation and sets usage behavior resulting in slowly increasing Google imposed sending limits. 

      But given that you’ll be using a G Suite account which has a better sending reputation in comparison to free Gmail accounts, being able to send a total of 3000 to 4000 emails per day should not be an issue. For non-commercial, low-volume campaigns, we also tend to push these through via our SendGrid account to ensure a timely delivery.

  37. steve jb

    Let’s say i use a google sheet that has 5000 emails and I start a spread out campaign and start with 100 email/day. Can I make changes to the amount of emails sent throughout the campaign?Like lets say after the second week i’d like it to be 200/day 3rd week 300/day and so on.

    • Marvin Quinsaat

      Hi Steve,

      Yes, just open the draft and then set the limit per day in your GMass settings then click the GMass button to save.

  38. JE

    I have about 50 gmail accounts…. do I have to purchase 50 subscriptions (that would be crazy) or can I simply login to each account using my 1 gmass subscription?

    • Marvin Quinsaat


      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.

  39. Alex

    Hello, my instructor says that I can send up to 10,000 emails per day. But, my research says that G Suite can only send 2,000 per day. But, my instructor said that a bulk of recipients is considered 1 send. So, is it true that I can send up to 10k in 24 hours due to 1 bulk of recipients being considered 1 of 2000 emails sent? Or 10k is really just 1 command of sending 10k emails over 96 hours?

    Ugh. I thought this was so awesome that we can now send larger emails . . . Until today when I sent a large email and GMass used a third party . . . SendGrid . . . and SendGrid was marked as SPAM for many of my emails. So this truly sucks . . . now because they are marked as SPAM, my emails are not going through. I thought the major benefit of GMass was NOT being tagged as SPAM. So frustrated right now.

    Can you help with after generating the SMTP connectivity with sendgrid ,what will be the further process to send a mass email of data more dene 2000

Anyways thank you for information.
