The MailBluster daily email sending capacity depends on the SMTP provider you use, such as Amazon SES, Postmark, Mailgun, or SMTP2GO. MailBluster does not set a sending limit. Your provider account determines the maximum number of emails you can send each day.
For example, after moving out of Amazon SES Sandbox, AWS gives a daily limit of 50,000 emails. This limit can increase based on your account’s sending reputation. Other providers, like Postmark, Mailgun, and SMTP2GO, have their own limits depending on account type and history.
Follow email best practices and maintain a strong sending reputation to maximize your daily email capacity with MailBluster.
