Sendgrid API Change

Hello WP Mail’s team!

We are using WP Mail SMTP with SendGrid configured as the mailer (API key integration).
SendGrid has announced an upcoming API endpoint change as part of their migration to Sinch:

• Current endpoint: https://api.sendgrid.com/v3/
• New endpoint: https://api.sinch.com/email/v3/

According to SendGrid, all API requests will need to use the new endpoint structure starting next week, with legacy endpoints supported until February 2027.

Could you please confirm:

1. Whether WP Mail SMTP already supports this endpoint change, or
2. If support for the new Sinch endpoint will be included in an upcoming plugin update.

We do not have any hardcoded SendGrid API calls in our application; all email delivery is handled internally by WP Mail SMTP.

Thank you for your answer!
