If you've ever seen "You have reached a limit for sending mail", you've hit one of Gmail's daily caps. They're lower than most people expect, and they count recipients, not emails.
The limits
| Account | Recipients per day |
|---|---|
| Free Gmail (@gmail.com) | 500 |
| Google Workspace, trial | 500 |
| Google Workspace, paid | 2,000 |
One email to 500 people uses up a free account's whole day, the same as 500 separate emails. To, Cc and Bcc all count.
What happens if you go over
Gmail stops sending from that account for a while. According to Google, you can usually send again within 1 to 24 hours. Hitting the limit again and again makes Google more suspicious of the account, so it's worth avoiding.
How to send more without getting blocked
- Spread the load over several accounts. Five accounts at 300 emails a day each is safer than one account pushed to the limit.
- Stay well under the cap. New accounts especially shouldn't start anywhere near 500. Begin with a few dozen a day and build up.
- Space the emails out. A burst of hundreds of emails in a few minutes looks automated. A short random pause between emails looks normal.
- Warm up new accounts first. See how to warm up a new email domain.
Doing it with ZeroPhantom
Our Windows senders let you add several Gmail accounts, set a daily cap per account and add pauses between emails, so you stay inside the limits automatically. If your accounts are new, run them through warmup for a couple of weeks first.
