Integration: Wordpress

I am currently using the plugin Postman SMTP Setup, which also accepts APIs (SendGrid, MailerSend which connect with API) and the plugin team continuously adds new mailers. It would be great if you guys could contact them so they could add you as an option (they have both free and premium plans, but everyone can do a complete setup on the free plan, also they are well-maintained unlike other unsafe free Wordpress SMTP plugins). I prefer connecting through API as it’s a better connection. I know developers use mailtrap a lot, but I think mailtrap is user-friendly enough to also attract more standard wordpress-based webshops with mostly plugins.
