Problem
You are unable to send more than 500 emails in a 24 hour period and receive a bounce back message about the sending limits after exceeding.
Environment
- Gmail
Solution
After you convert from a free trial account to a paid subscription, your account sending limits automatically increase when both of the following are true:
- Your domain has cumulatively paid at least a certain amount.
- At least 60 days have passed since reaching that payment threshold.
Cause
To keep systems healthy and accounts safe, Google limits the number of Gmail messages users can send per day, and the number of recipients per message. After the trial period is over, the account is kept with trial-like limits until the requirements are met.
