Verify Sources

This content explains the Verify Sources feature of MxToolbox's Delivery Center.

What Is a Verified Source?

Verified Sources are the collection of email services you use to send email. For example, you might send emails from:

  • Google GSuite or Office 365
  • Marketing tools like MailChimp, Marketo, SalesForce, etc.
  • In-house web apps or ESPs like SendGrid or Mailgun
  • On-premise email servers

It's extremely important that you keep your Verified Sources accurate and up to date. We use this information not only during your initial setup, but also for ongoing conifguration tweaks and crtical security alerts. Statistics reported on this page are based on DMARC aggregate data reported to us from the inboxes you send email to.

What Do the Values On This Page Mean?

Value Explanation
Outbound Email Source: A named sender of email like a third-party email service, such as MailChimp, Office365, etc. Where appropriate, the IPs of the email source are displayed.
DMARC Compliance: This is the ultimate score we're aiming to increase for every email source you send from. This indicates the volume of email sent from your Verified Sources that either passes all SPF validation mechanisms or passes all DKIM validation mechanisms.
SPF Pass Rate: This displays the rate and count of emails that, during SPF validation, the email passes both authentication tests and alignment tests. A pass in both of those categories for an email means that the email is DMARC Compliant.
DKIM Pass Rate: This displays the rate and count of emails that, during DKIM validation, the email passes both DKIM authentication tests and alignment tests. A pass in both of those categories for an email means that the email is DMARC Compliant.
Email Volume: This is the total volume of email that has been sent by the Verified Source during the period selected. Note: Not all inboxes support DMARC and send reports, thus the email volume reported may not match 100% with the volume of email you're sending.

These stats are critical in prioritizing which Outbound Email Source needs to be fixed to ensure high DMARC deliverability.

Don’t See an Outbound Email Source or IP Address You Send Email From?

Click on the orange "Add Verified Source" button to load a list of Outbound Email Sources and IP addresses that we detected have been sending mail for your domain or forwarding your emails.

Once you have found the missing Outbound Email Source or IP that was missing from the Verified Sources list, simply select the checkmark box to the left of the Outbound Email Source and it will be added to your Verified Sources.

Note: It typically takes 24 hours for new sources to appear in the Un-Verified Sources list after you first send email from the source. (e.g., If you send an email campaign on Monday, you should see that data on Tuesday.)

Suggested Sources From Your SPF Record

We perform a lookup on your existing SPF record to get a list of all sending sources you identify as being allowed to send email for you. These sources are identified by an SPF Mechanism. We are then able to suggest them to you as a "Verified Source".

You should choose to accept or reject any sources that appear here to ensure that your Verified Sources are as accurate as possible. Accepting will move the source to your Verified Sources where it will be used to ensure your email deliverability settings and data are accurate. If you reject a source, it will be dismissed until the next time we check your SPF record.

Adding a Source with No Data

Sometimes you want to add an Outbound Email Source that hasn't been detected yet. Maybe it's a new server or only occasionally sends email for you. At the top of the Add a Verified Source section, you will find an input bar that contains a list of Outbound Email Sources. Select your providers, then click the green "Mark as verified" button.

I’ve Classified All My Outbound Email Sources as Verified Sources... Now what?

Once you have listed all sources in the "Verified Sources" section, you should pay direct attention to the rate numbers for DMARC, SPF, and DKIM, as raising those scores is the next critical item. Pay priority attention to those sources which have the lowest DMARC scores and send a significant amount of email, as improving those will have the greatest immediate impact.

Renaming a Verified Source

You can easily name or rename Public Verified Sources by selecting the pencil icon to the right of the name, entering the new name, then selecting the green checkmark.

Voila! The source has now been named or renamed. This has no effect on your mail delivery, but is useful to make the reports and tools easier for you to understand. For example, if you use Google Apps for your east coast office and Office 365 for the west coast, then you might name them "East Coast Office" and "West Coast Office" for clarity.

No Data Sources

You don't want sources that don't send email for you to be included as a Verified Source because they can skew your data and show you confusing results. Sometimes there will be sources that have no data for several or more days. If we see a source that has no reported email volume for 30 days, we will highlight this for you on the page and recommend removing the source.

You should review these highlighted sources and remove any that don't send email for you. You should also pay attention to any sources that only send email occasionally. For example, a newsletter that is only sent every 30 days.
