Set up SendGrid with Regal Send
Updated September 20, 2026
SendGrid SMTP integration lets Regal Send route new WordPress emails through SendGrid. This guide explains the SMTP profile, sender verification and safe testing steps.
Before you begin SendGrid SMTP integration#
- Administrator access to WordPress and SendGrid.
- A verified sending address or domain.
- an API key with Mail Send permission.
Configure SendGrid in Regal Send#
- Open Integrations in Regal Send and select SendGrid.
- Open the provider setup guide linked in the panel and create or copy an API key with Mail Send permission.
- Enter the SMTP host, port, username and secret. TLS on port 587 is the normal starting point unless the provider states otherwise.
- Save integrations, set a verified From Email, then open Test Email and send a test to an address you can read.
Use the username shown by SendGrid for SMTP authentication and use the API key as the SMTP password.
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 SendGrid official setup documentation for provider-specific account, sender and credential steps.
