SMTP emails not picking up the correct From name and From email

Have you disabled EasyWP SMTP or completely deleted it? If you’ve deleted it and it still shows the old from address, most likely some database entries are leftover. To fix:

  1. Depending on how you’ve setup Post SMTP mailer, try changing the From address details in this plugin’s settings
  2. Manually change the From address in WordPress using filters in functions.php. See method 3 at this link

Please note that this doesn’t remove any database entries created by the EasyWP SMTP (if any).
