Limit on number of emails that can be sent from free Gmail account?

I need to send the same email with a Microsoft Word 2016 attachment to around 4,800 different email addresses.

These are all email addresses that have either emailed me or that I have emailed in the past.

I will be emailing around 100 of these email addresses each time until I have emailed all 4,800 email addresses using my free email account which is set up in Outlook 2016.

Does Gmail have a limit as to how many emails addresses can be emailed over a certain time limit (such as a day) before they will halt the emails (suspecting that spam is being sent)?

by default this limit is 500 if its free account or gmail trial (professional account)

for gmail business account limit is 2000 I believe

better you could create gmail group and add all your recipients in that, that would work

If by chance you breach there rule, they will block your email sending rights for 1 to 24 HRS

If you are using professional gmail, contact there support to get better solution for your requirement

Sending limits for Gmail:



Sounds like you are using a personal account, so the relevant section from the link above appears to say:

You may see this message if you send an email to a total of more than 500 recipients in a single email and or more than 500 emails in a day sent.

When you get this error, you should be able to send mails again within 1 to 24 hours.

To prevent this from happening in the future, try creating a Google Group of all your email recipients and sending the message to that group's email address.

Hope that helps,

No, I think they are referring to a GSuite account that is in the trial period, so you aren't paying for it yet.

I doubt you will find ANY cloud based service that does not have a limit on the number of messages sent. Office 365, (assuming the link is current)  has a limit of 10000 recipients per day, which may work better for you.

Another option might be to "roll your own", and send with software actually designed to send mailouts.

Machmailer or MailthemPro could be worth considering.
Andrew LeniartFreelance JournalistCommented:

Due to the limitations described by the other experts above, I'd suggest a perfect way around this problem is to use a locally installed Mass Mailing software package like SendBlaster. (Free version available)

I recently wrote a review of Sendblaster and its use on Experts Exchange which you can take a look at here:

This software will allow you to schedule your mass mailouts so that you don't exceed your limits and can continue to use your Gmail SMTP server, or alternatively, use a combination of two SMTP servers to send your mailouts. A host of information is provided in the above article.

I hope that's helpful.
