Making sure your email list doesn’t contain invalid email addresses before you send a campaign is crucial for protecting your sender reputation and maximizing deliverability.
Email verification tools can help you make sure that your email list is free of spam traps, as well as invalid, disposable, and catch-all email addresses. Here’s our list of the best email verification tools in 2023.
1. Email Verifier by Hunter
Hunter’s Email Verifier uses a comprehensive verification process that includes performing checks at multiple levels to ensure every email address on your list is safe to email. For each email address, it checks for valid format and presence of MX and SMTP records.
It also detects disposable email addresses and those created using free email providers such as Google and Yahoo. Finally, it runs an SMTP check to see if an email sent to the email address will bounce or not. Email Verifier can also detect email addresses from accept-all domains.
You can use Email Verifier to verify a single email address or a list of email addresses. There’s also the option to use Hunter’s API to verify email addresses anywhere on your website or in-app.
Hunter integrates with popular CRM solutions such as Salesforce, HubSpot, Pipedrive, and Zoho CRM, as well as offers additional custom integrations through Zapier.
There’s also a Google Sheets add-on you can use to verify email addresses within a Google Sheets spreadsheet.
Apart from verifying email addresses, you can also use Hunter to:
- Find anyone’s email address using the Email Finder
- Uncover all the email addresses associated with a specific domain using Domain Search
- Send automated cold email campaigns using Hunter Campaigns
2. ZeroBounce
