No, MailBluster does not support Custom SMTP.
Currently, MailBluster only supports sending emails through Amazon SES, Postmark, and Mailgun. You cannot use your own custom SMTP server outside of these providers.
To use these services, please ensure the following:
- For Amazon SES, you must have a verified, approved, and out-of-sandbox AWS account.
- For Postmark and Mailgun, you will need a verified domain and an active account with the respective provider.
