Setting up Heysender with your Shopware e-commerce store is super easy. In Shopware simply navigate to Settings > System > Mailer
Now select STMP Server in the mailer configuration for Preferred email agent
Now setup the SMTP configuration with the data from your Heysender account.
Host: smtp.heysender.com
Port: 25, 2525, 587
Encryption: TLS
Username and password are found on your Heysender account. Navigate to Domains in the menu on the left side, now click the domain in question and select STMP users.
If you have not created an SMTP user yet, click Add SMTP user.
Then grab the username and password and put it into your Shopware backend. Sender address is the same as username.
In the example above we have used port 25 for our SMTP setup. But you are free to use either port 25, 2525 or 587.
Finish by clicking Save. Now you are sending your transactional emails from the shop through Heysender.
