Newsletter Weight when using SMTP
When sending commercial or transactional emails through the Mailpro SMTP Relay server, the weight of the message plays a very important role in its sending.
You should know that each 500 KB of weight will equal one credit on your account. Consider that the maximum weight of a message can be 40MB, including all the message content and attachments contained in your mail.
If you need to send larger messages, through the Mailpro SMTP Relay server we recommend that you contact our technical team.
The Mailpro team is more than willing to help you.
