Usage Notes

For Gmail accounts, you must use an App Password rather than your regular Gmail password. Enable 2-factor authentication first, then generate an app password.

SmartLead automatically validates SMTP and IMAP connections upon adding an account. If validation fails, the account is still created but marked with connection errors that you can fix later.

Enable warmup for new email accounts to gradually build sender reputation. Set total_warmup_per_day to start with 10-20 emails and use daily_rampup of 2-5 to increase daily volume gradually.
