Verify Email Address Deliverability with SigParser

Check if an email address is deliverable

Updated over a week ago

Why it matters?

Your email deliverability rate matters! This is why email marketers often use email verification to improve their deliverability rate. A low deliverability rate could result in you getting kicked off of your email marketing platform or your emails getting blocked.

Email verification is all about determining whether an email address is deliverable. There are a lot of data points that go into guessing whether an email address is deliverable. These include pinging the mail server silently, your latest interaction dates, bounces and third party tools such as Clearout in our validation process. We strive to be right 99% of the time. For most email marketers it is better to maintain high reputation for deliverability than to deliver to every email address. Additionally, you can use other metrics in SigParser to determine which email addresses you want to send emails to such as the number of emails received or sent to an email address or the latest date or even job title or custom fields you define.

🔥 Accuracy better than normal email validators

SigParser is better than normal email validation services because SigParser is able to look at your data combined with the results of third party email validation services. SigParser is able to see if your last email to a contact bounced or if you recently had email communication with an email address which normal email verification services can't do.

⚠️ Not ideal for job change tracking

We've had customers try to use email verification for determining whether someone has left a company or not. If job change tracking is critical for contacts then email verification isn't the right tool. This tool only tries to tell you if an email address is likely deliverable, not if the employee is still there. Often an email address is still deliverable after someone leaves.

Instead we suggest using our Job Change enricher within SigParser to determine which contacts have moved jobs. It is more expensive but will give better results including their current job title and past jobs and will update the email address on the Contact record to their new position.


Get Started with Email Address Verification

  1. Go to the Contacts page

    • Suggest starting with the predefined view All Email Address Details and filtering down to just Email Status equals "Missing"

    • Select the checkbox next to the records you want to validate.

    • To select all contacts on the page, use the top-left checkbox on the grid.

  2. Start Validation

    • Click the Enrich button > choose Contact Email Validation

  3. Review & Confirm

    • You’ll see how many contacts will be enriched and how many credits will be used.

      • If you don't have enough credits on your account you'll be given the option to purchase additional credits.

    • Click Enrich Records Now to begin.

  4. Monitor Progress

    • Enrichment starts within a few seconds or minutes, depending on volume.

    • You can close the window—results will continue to update and can be viewed later in the Enrichment page.

You’ll only be charged credits for successful validations. Failed attempts won’t cost you anything.
