A: Dear matteo77,

Thank you for reaching out to us. In theory, we do not impose a limit on the number of emails you can send. However, the sending limit depends on the mailbox you are using.

Gmail Mailbox: We recommend sending no more than 400 emails per day to avoid potential restrictions.
SMTP Mailbox: You will need to confirm the daily sending limit with your relevant technicians or suppliers, as this can vary.
Please feel free to reach out if you have any more questions!

Best regards,

Avery Bai
