Supercycle sends its own emails to customers when something happens on their rental, return, or subscription, such as a return being requested or credits being returned to a membership. Each email is a template you can reword under Languages, and the branding, reply-to address, and delivery are set under Emails.

Emails are sent from [email protected]. To send from your own domain, connect a custom SMTP server or contact support from the app.

​
Custom SMTP

By default, Supercycle delivers all transactional emails through its own mail provider. To send them from your own domain and mail infrastructure, connect a custom SMTP server. When it’s on, customer emails go through your server with the From address you set. If the integration is turned off or removed, Supercycle falls back to its default provider, so no emails are lost.
Use a dedicated transactional email service such as Postmark or Resend rather than a general-purpose mailbox. They offer better deliverability, bounce handling, and analytics for transactional mail.
You need these details from your SMTP provider, for example Postmark, Resend, Amazon SES, SendGrid, Mailgun, or your own mail server:
  • Host. The SMTP server hostname, for example smtp.sendgrid.net.
  • Port. Typically 587 for STARTTLS or 465 for implicit TLS.
  • Username and password. Credentials for an account authorized to send mail.
  • From address. The address in the From header. It must be authorized by your provider, with SPF, DKIM, and DMARC records on your domain.
  • Authentication method. Usually plain. login and cram_md5 are also supported.

Connect an SMTP server

1

Open emails

Go to Emails.
2

Turn on Custom SMTP

Under Custom SMTP at the bottom of the page, turn the section on, then select Configure SMTP server.
3

Enter your SMTP details

Enter Host, Port, Username, Password, and From address. Set an Authentication method and, if needed, a HELO domain. Leave Enable STARTTLS ticked unless your provider requires otherwise.
4

Save

Select Save. Your password is encrypted at rest.
5

Send a test email

Select Send test email. Supercycle sends a test message to the shop’s contact email address with the credentials you provided. If the test fails, the error your SMTP server returned is shown so you can correct the host, port, credentials, or sender address.
To update credentials, select Edit on the Custom SMTP section. Leave the password blank to keep the existing one. To stop using your server, turn the section off or select Remove. Supercycle reverts to its default mail provider for all future emails.
