If you are selling B2B, it is fairly easy to figure out how to guess a corporate email address. The reason why is that all corporate email addresses are usually some sort of combination of details from the persons first and last name and the domain name for the company’s website.

Common Email Naming Conventions
Here are some examples of the most common naming conventions that companies use.

  • [First Name]_[Last Name]@websiteaddress.com
  • [First Name].[Last Name]@websiteaddress.com
  • [First Name]@websiteaddress.com
  • [Last Name]@websiteaddress.com
  • [First letter on first name][Last Name]@websiteaddress.com
  • [First Name][First letter of Last Name]@websiteaddress.com
  • [First Name][Last Name]@websiteaddress.com
  • [Last Name][First Name]@websiteaddress.com
  • [Last Name].[First Name]@websiteaddress.com
  • [Last Name]_[First Name]@websiteaddress.com
  • [First Name]-[Last Name]@websiteaddress.com

Figuring Out Which Email Address is Correct
Even though we can look at that list and know that we can guess someone’s email address and that it is likely one of those, we still have to go through some sort of process to get to the right email address. Here are a few options:

The crudest but very effective way to use this knowledge on how to guess an email address is to simply plug your prospect details into a format that you think might work and send off an email and see if it bounces or not. If the email comes back as “Undeliverable”, you can then use the process of trial and error and try another format until you send an email that does not bounce back.

Use an Email Verifier
There are some tools out there that you can enter an email address into and run a test and the software will commutate out to MX record databases on the internet and verify whether the email address that you guessed is verified and correct.
