Set up SendLayer with Regal Send

Updated September 20, 2026

SendLayer SMTP integration lets Regal Send route new WordPress emails through SendLayer. This guide explains the SMTP profile, sender verification and safe testing steps.

Before you begin SendLayer SMTP integration#

  • Administrator access to WordPress and SendLayer.
  • A verified sending address or domain.
  • SMTP credentials or an SMTP API key.

Configure SendLayer in Regal Send#

  1. Open Integrations in Regal Send and select SendLayer.
  2. Open the provider setup guide linked in the panel and create or copy SMTP credentials or an SMTP API key.
  3. Enter the SMTP host, port, username and secret. TLS on port 587 is the normal starting point unless the provider states otherwise.
  4. Save integrations, set a verified From Email, then open Test Email and send a test to an address you can read.

Confirm the sending domain before testing delivery and use the credentials displayed in SendLayer.

Troubleshooting#

If sending fails, confirm that the From Email is verified, the host and region are correct, and the saved secret is current. Use the Email Logs diagnostic and the provider account activity to identify a rejected sender, invalid credential or account restriction. Do not paste credentials into support requests.

Official help#

Use SendLayer official setup documentation for provider-specific account, sender and credential steps.
