SMTP relay service

Using MailUp as a SMTP relay service for transactional emails

You can use MailUp not only to run great email campaigns, but also to send transactional emails in a high-deliverability, high-capacity environment.

You can send transactional emails in two ways:

• With our SMTP relay service, called SMTP+ and covered in this section.
• With our APIs for transactional email

Both SMTP+ and the transactional email APIs are included at no additional cost with every MailUp account, leveraging MailUp's innovative pricing model.

This means that MailUp users can...

• Send transactional email messages with high deliverability from a Web app or ecommerce store
• Track opens and clicks on those messages
• Manage bounces and feedback loops automatically
• Add this new sending channel at no additional cost!

Getting set up in just a few clicks

Configuring your MailUp account for use as an SMTP relay service only takes a few clicks.

• Create a new list
• Navigate to Settings > List settings > SMTP+
• Add a SMTP relay user
• Use those credentials in your application or Web site
