The number of emails you can send each day depends on your Amazon Web Services (AWS) account, specifically through Amazon SES (Simple Email Service), which sets the daily limit, not MailBluster. Initially, after moving out of the Amazon SES Sandbox, AWS provides a daily sending limit of 50,000 emails per day (within 24 hours). This limit may vary, potentially reaching 60,000 or even 100,000 emails per day, depending on your account’s previous sending reputation.
MailBluster uses your AWS account to send newsletters and marketing campaigns since it doesn’t provide an SMTP server or services. If you follow best practices and maintain a good sending reputation, Amazon SES may increase your daily sending limit upon request.
