Using email verification is a must for ensuring that your email list is accurate, maintaining a good sender reputation, improving email deliverability, and optimizing your email campaigns.
No. mailfloss’ email verification service doesn’t send emails to the email addresses being verified but uses other methods, such as our proprietary Deep Clean Engine for running tests, syntax validation, domain and mail server verification, and more.
There are two ways to verify email validity. First, you can manually send an email to each address, which is time-consuming and potentially illegal depending on jurisdiction, or, use email verification to automate this process, guaranteeing an accurate email list and saving time for other important business activities.
We know how tricky it is to achieve perfect email verification. However, you can trust the reliability of our service, powered by our Deep Clean engine.
