Deliverability Tools

A more advanced set of tools, these were designed to aid our customers diagnose deliverability issues with their email servers and inbox placement. These new tools include an Inbox Placement Tester, Email Server Tester, and a newly-launched Blacklist Monitoring service. These work in conjunction with our core business service, email list validation.

Email Server Tester

/deliverability-tools/email-server-tester/

The Email Server Testing Platform analyzes your email headers, according to best practices set by mailbox providers, to ensure that your mail server is setup and configured correctly This tool offers an incredibly detailed look into your mail server settings. Here, you’ll be able to diagnose any deliverability issues, and forward the results to your company’s postmaster. Follow the steps below to begin testing:

You’ll be presented with a randomly assigned email address. The address pictured is for illustrative purposes. Send an email to the address from the mail server that you want to test:

Once you send the email, please allow a few minutes for your results to appear. Below the test email, you’ll see the following table.

Inbox Tester

/deliverability-tools/inbox-tester/

The Inbox Tester is used to check if your emails/newsletters will make it to your recipient’s inbox. This test will allow you to send an email to different mailbox providers around the world and quickly check to see the placement of that email.

We make available over 20 different mailbox providers, located around the world. This’ll help you understand how different mailbox providers handle your emails. When testing, if you send out a single email with a lot of To's and CC's addresses on it, it can be flagged as spam. Please send out multiple emails when testing with fewer To/CC's for better results.

It is really simple to get started:

  • Enter a testing file name (this is to help you identify individual tests)

  • Choose which mailbox providers you wish to test by selecting from the dropdown

  • Click ‘Create New Test’

  • Copy your custom test code from the box below, and insert into the footer of your email

  • Copy the newly generated email addresses and add them to a new mailing list in your email marketing service

    Please note: Some mailbox providers will not deliver one-word emails, so be sure to test with a natural email or newsletter. Once you create your first test, the results will appear in the table below.

Inbox Results

    Description
  • Inbox
    Your email successfully reached the recipient’s inbox.

    When emails are missing it's usually a result of a mis-configuration of your mail server (Use our Email Server Tester to diagnose), a virus was detected, or your IP/Domain Name is being blacklisted.
  • SPAM
    When emails are marked spam, it's usually a result of the content or lack of content being sent, your IP hasn't been warmed up, or a mis-configuration of your mail server (Use our Email Server Tester to diagnose).

Blacklist Monitoring

/deliverability-tools/blacklist-monitoring/

As part of our Deliverability Tools, our Blacklist Monitoring service will allow you to verify your status with over 200 different blacklists. And if your domain or IP is flagged, you’ll know which blacklisting company to contact about being delisted. You’ll be able to enter not only your domain (example.com), but also your IPv4 (123.123.123.123) and IPv6 (2001:db8::8a2e:370:7334) addresses. We recommend monitoring all your IP addresses that you use to send mail and domain names you send mail from, as this will provide greater monitoring success. All subscription levels, including Freemium, will have access to the Blacklist Monitoring service.

If you’re unsure of what your domain or mail server IP address is? Use Google’s free DNS tool here.

Before setting up a monitor, please create a mailing contact list. This allows you to route your alerts to the proper team-member within your organization, or even outside vendors. If you haven’t done so, you’ll be prompted by the monitoring wizard.

Once you have a contact list set up, navigate to the Blacklist Monitoring page in the member’s dashboard. When you’re ready to create a monitor begin by clicking on ‘Add New Monitor’.

When you’ve entered the proper information, click ‘Insert’ and your blacklist monitor is set up.

Depending on the level of your Deliverability Tools subscription, you’ll have a set number of monitors available to you. Also, your subscription level determines the frequency of which we check the domain or IP you’ve provided. Please see the table for a breakdown;

Note: The number of blacklists we monitor changes, so be sure to include not only your domain but also your IPv4 and IPv6 addresses.

You’ll now be able to toggle which blacklists you’d like us to monitor, by default all are set initially to ON.

Our alert system will notify you when your domain or IP has been initially scanned, then, only if the status of your domain or IP address has changed, i.e. it was added to a blacklist or delisted from one. The number of backlists we check against will fluctuate. To ensure proper monitoring, please make sure to monitor your domain, IPv4 and IPv6 addresses.
