A completely

refreshing new way to test email.

Catch local emails HELO exposes an SMTP server and catches the outgoing emails from your application instead of sending them to their actual recipient.

Unlimited Inboxes Receive emails in a dedicated inbox per application by setting a unique name per project. There is no limit on the number of inboxes.

Simple content Review HTML representation, text, source code, raw, headers–we got you covered. Check your emails before you deploy to production.

View Inspector Install our open-source helper package to debug Laravel views or create own helpers to debug mails of your favorite framework.

Link Checker The automated link check verifies that all links in an email are valid and return an HTTP 200 status code. Don't send emails with broken links again.

Spam Report If activated, HELO automatically checks the Apache SpamAssassin score of your incoming emails. Never lose a mail in your users spam box again.

Forward Emails Forward emails from HELO to team mates or clients for review. Send them to a testing service to see how they look in different email clients.
