Community Q&A
How do I optimize WP Mail SMTP for better performance?
Use a dedicated mailer service like SendGrid, Mailgun, or Amazon SES instead of the default PHP mail function to offload processing from your server.
Does WP Mail SMTP slow down my WordPress site?
It can if configured to use local server mail. Using an external API provider ensures that email processing happens off-site, keeping your site fast.
