HELO

Local Mailboxes

The easiest way to catch incoming emails in HELO is by using local mailboxes. The app creates local mailboxes automatically, when it receives an incoming email from your application. There is no need to manually create these mailboxes.

Email details#

Once HELO receives an incoming email from one of your applications, it sends out a notification and shows you the email details in the application UI. Here is how such an example email might look like:

The user interface gives you all the information about the incoming email, such as the sender, recipient and possible CC and BCC addresses.

You can get more information about the incoming email, by looking at the different tabs. They include information such as the raw email message, the SMTP headers or spam report information.

HELO comes with a built-in link checker, that makes it very easy to determine if your outgoing emails contain any broken links. The link checker is enabled by default and will try to automatically perform a HEAD request to all links of your email. If the HEAD request does not succeed, it tries to perform a GET request instead.

The GET request might not be the desired behaviour and can break one-time links. If an email verification link only works one time and HELO performs the GET request to this link, your application marks the email as verified and additional requests will fail.

If you are testing emails with one-time links, HELO allows you to disable the link checker feature in the settings.

Spam report#

When HELO receives an incoming email, it automatically performs a SpamAssassin check on the email message. The SpamAssassin score tells you how likely it is, that your email ends up in the spam folder of your user. Please be aware that this score is only one indicator and is not a guarantee that your email will go through. When you actually send out your email a lot of additional factors come into play, when receiving email servers calculate their own spam score – such as the server that your email sends.

The spam report gives you detailed information of the SpamAssassin scoring.

Testing#

HELO allows you to easily test the design of your email on multiple different email clients. HELO uses [email protected] – it requires that you have a Testi account. Testi includes some tests in the free version, so you can check out if you think that the service is helpful to you.

Once you login with your Testi credentials, you can create new tests, choose which email clients you want to use for testing and get the results in the HELO UI:
