MailerSend

MailerSend is a cloud-based email service that focuses on sending emails automatically from your apps or websites. Unlike regular email services for marketing campaigns, MailerSend specializes in sending individual messages triggered by user actions.

The platform provides both an API for developers and a simple interface for non-technical team members. You can send emails through code or by using their built-in SMTP service. The system tracks every email you send, showing you when it was delivered, opened, or if there were any problems.

MailerSend helps keep your emails out of spam folders with built-in tools for checking email addresses before you send and monitoring your sending quality. You can also receive incoming emails and process them in your application automatically.

ImprovMX

ImprovMX is a cloud-based email forwarding tool that connects your custom domain to your existing email inbox. Instead of setting up complicated email servers or paying for expensive hosting, you simply point your domain to ImprovMX and create email aliases that forward to your personal email.

For example, you can receive emails at [email protected] and have them arrive in your Gmail inbox. You can also send emails from your custom domain using their SMTP service, making your messages look professional and consistent.

The service includes features like catch-all addresses, custom routing rules, email logs for tracking, and an API for developers. It works fast, with most emails forwarding in under 5 seconds, and maintains a strong uptime record for reliability.
