Repository metrics are context, not quality scores. Active installations measure adoption and can strongly reflect a plugin’s age and historical popularity. Ratings, recent updates and “Tested up to” metadata also do not guarantee modern code, error-free operation, security, feature completeness or suitability for a particular site.

Overview
About this plugin
Oderland SMTP & Postal Mailer is a plugin that allows you to send transactional emails using SMTP or Postal API. Easy-to-use for e-mail logging and making sure your e-mails make it all the way to your intended target.

What is SMTP and why do you need it?
SMTP (Simple Mail Transfer Protocol) is the standard that ensures that emails actually arrive at their destination. It’s a protocol that delivers your email between servers when you click “send” in your email client.
You could say that with an SMTP plugin or service, you want to confirm to the email servers that what you’re sending isn’t spam, which lends authenticity to your mailings.
