Mailosaur vs Mailtrap opinions
Our marketing team sent out emails that were hard to read on an IPhone. We used the email previews feature from Mailosaur to check that my team had fixed it.
Create email addresses on demand. Send and receive real emails and attachments from code. Rest API and developer kits available.
MailCatcher runs a super simple SMTP server which catches any message sent to it to display in a web interface. Run mailcatcher, set your favourite app to deliver to smtp://127.0.0.1:1025 instead of your default SMTP server, then check out http://127.0.0.
Dummy SMTP server that sits in the system tray and does not deliver the received messages. The received messages can be quickly viewed, saved and the source/structure inspected. Useful for testing/debugging software that generates email.
Pacomail is a test mail server solution that allows testing email without sending them to the real users of your application. Code, preview, test, and collaborate using a development tool designed for email.
Pacomail vs Mailtrap opinions
I like Pacomail as an alternative to mailtrap because it has a well executed feature of debugging transactional emails and it is RGPD compliant !
Ethereal is a fake SMTP service, mostly aimed at Nodemailer users (but not limited to). It's a completely free anti-transactional email service where messages never get delivered.
