Mailtrack campaigns let you send up to 10,000 emails (2,000 per day during 5 days), but take into account that the maximum number of emails you can send, though, depends on the limits Google has placed on your Gmail account. Please check your sending limit with Google.
If you exceed Gmail's sending limits or if Google identifies potentially suspicious activity—such as suspected spam or violations of their terms of service—you might face issues. Please note that Google does not specify the exact reasons for these actions.
At Mailtrack, we use Gmail's sending service to guarantee you the highest deliverability. For this reason, if you encounter any issues with sending limits, you'll need to reach out to Google for resolution.
