Gmail sending limits: 500 a day, and how to send more

The limits Google enforces

The day is a rolling 24 hours, not midnight to midnight. A "recipient" counts every address in To, Cc and Bcc, so one email to 100 people uses 100 of your 500. Google publishes these numbers in its Gmail sending limits help pages; they can be lowered temporarily for new or suspicious accounts.

What happens when you hit the limit

Gmail shows "You have reached a limit for sending mail" and blocks sending for up to 24 hours. Repeatedly hitting it, or sending to many addresses that bounce or mark you as spam, can get the account suspended. That is why bulk tools should stop before the limit, not at it.

How MailBrother stays inside the limit

• One email per recipient. Each address gets its own message, which is what Gmail expects from a person.
• 90% ceiling. The default daily portion is 450 on Gmail and 1,800 on Workspace, leaving room for the emails you send by hand.
• Split sending. A 2,000-address campaign on a Gmail account is sent as 450 a day for five days, automatically, in the same campaign with one report.
• Pacing. Set a delay of 20–60 seconds between emails so a campaign does not look like a burst.
• Automatic pause. If Gmail reports the limit anyway, the campaign pauses and resumes when the window resets.

How to send more than 500 a day

1. Move to Google Workspace. $7/user/month gives 2,000 a day and lets you send from your own domain, which also helps deliverability.
2. Add senders. A Team plan lets several colleagues send the same campaign from their own accounts; five Workspace accounts cover 9,000 a day.
3. Spread the list. Split sending across days costs nothing and keeps the account healthy.
4. Do not use tricks. Rotating free Gmail accounts or sending through Bcc gets accounts suspended and lands in spam.

Limits are not the only thing that matters

Staying under 500 does not keep you out of spam. What does: a list of people who expect your email, a real subject line, a plain-text-looking body with one link, an unsubscribe link, and a clean list without dead addresses. MailBrother marks bounces and unsubscribes in every campaign so you can remove them before the next one.
