Best Email Verification Tools in 2024
In 2024, email verification is more critical than ever.
Without it, businesses will struggle to avoid high email bounce rates and improve email deliverability rates. Today, inboxes are overflowing with messages and spam filters are getting more aggressive; these are compelling reasons to keep your email list clean and up-to-date. As email use becomes more popular, you need to ensure mailbox providers see you as a trusted sender.
The right email verification tool can help you:
- Avoid bounced emails,
- Reduce the risk of getting blacklisted,
- Improve your email marketing performance.
Below, we’ve put together the email best email verification tools available this year, highlighting their features and how they can benefit your business.
What is Email Verification?
Email verification is the process of confirming whether an email address is:
- Valid,
- Deliverable.
The process involves checking if the address is formatted correctly, exists, and is capable of receiving emails. Email verification tools rarely send verification emails to contact lists; normally, they connect to the recipient’s SMTP server to verify the address.
Without email verification, your different types of email campaigns would not reach real people. You would see high bounce rates due to undeliverable emails. Invalid addresses could also cause a pile-up in the email outbox.
The process also helps avoid unnecessary email marketing costs associated with sending messages to invalid addresses. You need your messages to reach real, engaged recipients for your email marketing efforts to work.
Difference Between Email Verification and Email Validation
Email validation and email verification are often used interchangeably; if you’re confused, that’s completely understandable.
Theoretically, a verified email belongs to a recipient who has confirmed they wish to receive your messages. So when you send a confirmation email and they click through, you have a verified email.
As for email validation, it’s more technical. It analyzes the syntax, checks the domain, compares the email against blacklists or spam traps, and runs various checks to ensure it is a valid email address.
In case you did not set up a double opt-in method for email lead generation, we recommend you use a verification tool.
Email verification tools don’t email customers; this could lead to bounces. This is why most email verification tools are simply email validation tools; they use various methods to ascertain whether the ID is deliverable. It’s not quite the same as an email marketing subscriber who clicks on a link to confirm they want to receive your emails.
To sum things up: While a verified email and a valid email are two different things, most email verification tools are simply email validators.
