MailerSend is one of the email gateways Partnero can send your program’s emails through, alongside SMTP, Gmail, Brevo, and Partnero’s own built-in sending. Connecting your own MailerSend account lets those emails go out from your domain.
This is about sending email, not syncing data. MailerSend does not receive your partners or customers — for that, see Mailchimp or MailerLite.

​
Connect MailerSend

  1. In your program, go to Emails under Affiliate.
  2. On the Settings tab, click Setup next to Use MailerSend.
  3. Paste your MailerSend API token — see managing API tokens if you have not created one.
  4. Click Connect.
Once connected, MailerSend shows a green checkmark, meaning it is available for use.

​
Choose your sender

Connecting the gateway does not change which address your emails come from. Select your newly connected domain under Sender email, then click Update to save.

​
Disconnecting

Disconnecting stops your emails being sent through that account until you connect it again. If the domain you were sending from belonged to MailerSend, it is no longer selectable as a sender and you will need to pick another one.

​
Troubleshooting

Connecting the gateway and choosing the sender are two separate steps. Go back to Sender email, pick the MailerSend domain, and click Update.
MailerSend tokens are scoped. Make sure the token has permission to send email, and that you copied it in full — it is only shown once in MailerSend.
The sending domain has to be verified in MailerSend before it will accept mail for it. Verify the domain in your MailerSend account, then try again.
