    When To Clean Your Email List

    Cleaning email lists and scrubbing for invalid email addresses isnt a recurrent activity. Its often dependent on the size of your lists, how frequently you send email communications, and other factors. Smaller email lists with fewer contacts do not require the rigorous cleaning that a larger list may benefit from, according to SendGrid. They recommend the average email list should be cleaned approximately every six months for most email programs.

    Mailtrap offers a few other recommendations for email scrubbing frequency:

    • When new recipients are added
    • If its been more than one month since the last validation
    • If your hard bounce rate approached or exceeded 2 percent
    • If you have low open rates

    Reasons You Shouldnt Send A Test Email To Check An Addresss Authenticity

    The simplest way to check if an email address is valid is to send a test email. Simple, huh? If your test hard-bounces, the address isnt authentic and needs removing from your list.

    So, whats wrong with that?

    The more emails you test that way, the more hard bounces youll receive. As those hard bounces add up, even without sending out campaign messages, theyll damage your address reputation.

    If its enough to get you added to the spam lists, its going to affect your deliverability, and in turn, your sending and campaign metrics.

    The only way to use this method without it impacting your data is to set up a dummy email account from a different domain. Thats if you really want to pursue this method as an option, but you shouldnt.

    Additionally, you will just send spam messages to your recipients!

    There are much easier and more effective methods of validating your addresses.

  • temporary accounts used by scammers
  • accounts with a high degree of risk, threatening getting into the black list
  • accounts belonging to well-known complaint senders.

    Use An Email Finder Tool With Verification

    Most email finder tools offer the ability to verify email addresses. The key is to find a tool that automatically verifies your email address, rather than using up credits or charging you extra to take the verification step.

    A couple of things to look for:

  • Ideally you want a tool that gives you the option to verify emails from a prospecting tool like Sales Nav or upload your list, depending on your workflow.
  • You need a tool that only charges you for verified, up-to-date email addresses.
  • You have a few different options that meet both these criteria.

    • Hunter doesnt validate emails, so they are often outdated.
    • ZoomInfo can provide good data, but is often a budget buster for growing teams. It also becomes outdated quickly, as it will never update as fast as Linkedin profiles will.
    • Wiza finds and verifies email addresses, and is best used in conjunction with LinkedIn Sales Navigator.

    Wiza verifies email addresses as you scrape lead data from LinkedIn Sales Navigator.

    Youll need a Sales Nav account, but setting up your workflow ensures one thing: youre getting up-to-date, verified email addresses for the people youre trying to reach. Finally, youll only pay for verified email addresses.

    Heres how to verify an email address with Wiza:

    • Upload your .csv with the people you want to find email addresses for
    • Select Process List, then Scrape and Find Emails
    • After the search ends, youll be able to download your verified email addresses

    Stop Bouncing And Start Converting Your Subscribers

Remove the noise from your email marketing lists and focus on connecting with your real audience.
