Why verifying email addresses matters

Sending emails to unverified addresses is a waste of time and resources. Each bounce eats into your email sending limits and can negatively impact your sender reputation, making it harder for your legitimate emails to reach inboxes. A high bounce rate can even get your email service provider to flag your account.

More importantly, a valid email address is another channel to connect with a motivated seller. It demonstrates a level of professionalism and persistence. If you have gone through the trouble of skip tracing, you want that data to be as accurate as possible.

Basic checks for email validity

Before using any tools, perform a few manual checks. Look for obvious typos, misspellings of common domain names (like "gamil.com" instead of "gmail.com"), or unusual character combinations. If an email address looks suspiciously generic or includes many numbers, it might be a spam trap or an old, unused address.

You can also try a "soft" check by typing the email into your contact list or a popular social media platform's search bar. Sometimes, if the email is associated with a public profile, it will pop up, giving you a hint of its validity. This is not foolproof, but it is a quick first pass.

Using online email verification tools

There are many online tools designed specifically for email verification. These services check for domain validity, syntax errors, and sometimes even ping the mail server to see if the inbox exists without sending an actual email. Some tools are free for a limited number of checks, while others offer subscription plans for bulk verification.

When you use these tools, look for ones that provide a clear status like "valid," "invalid," "risky," or "unknown." A "risky" status might indicate a catch-all server or a temporary email, which you should approach with caution. Prioritize emails marked "valid" for your outreach.

The risks of unverified emails

Beyond damaging your sender reputation, sending to unverified emails can lead to other issues. You might be emailing someone who has nothing to do with the property or the seller, which is a bad experience for him or her and a waste of your time. You also risk hitting spam traps, which are email addresses specifically designed to identify spammers.

A high volume of bounces or spam reports can lead to your email domain being blacklisted. If that happens, nearly all your emails will go to junk folders, crippling your outreach efforts. It is always better to send fewer, higher-quality emails than many, unverified ones.

Integrating email verification into your workflow

Make email verification a standard step in your skip tracing workflow. After you receive your skip trace results, before you import them into your CRM or email platform, run the email addresses through a verification tool. This ensures your data is clean from the start.

Regularly audit your existing email lists for validity, perhaps once a quarter, to remove old or inactive addresses. This ongoing maintenance improves your email deliverability and keeps your communication channels clear, allowing you to focus on engaging with motivated sellers.

Questions people ask

Do I need to pay for an email verification tool?

For occasional use, you might find free tools that handle a small number of checks. For consistent, large-volume outreach, a paid service offers more accuracy, features, and higher limits, making it a worthwhile investment to protect your sender reputation.

What happens if I send emails to invalid addresses?

Your emails will "bounce," meaning they are not delivered. A high bounce rate signals to email providers that you might be sending spam, which can harm your sender reputation and cause your legitimate emails to be routed to spam folders or blocked entirely.

Is it okay to use this email for initial outreach?

As long as you are compliant with all local, state, and federal unsolicited commercial email laws, using a verified skip trace email for initial outreach can be effective. Always verify the email first to maximize your chances of reaching the intended recipient. (This is not legal advice).
