How to Choose the Best Email Verification Service
The best validation service is the one that fits all, or at least most, of your needs and has the highest accuracy rate at detecting invalid, undeliverable, and spam email addresses. The service should, at a minimum, check for correct syntax, catch-all servers, domain authentication, and SMTP authentication.
Other features that you may want to consider in a provider include:
- The speed at which the service checks your mailing list and provides results.
- Options for uploading your mailing list to the service. Do you need to verify only a few addresses? Do you do bulk verification? Do you prefer a software or cloud-based tool?
- Data security and GDPR compliance. Make sure the provider keeps your mailing list data private and follows standard data protection practices.
- A price that fits your budget. Some email verification services offer free or trial plans that are perfect when you are just starting with email marketing. You'll also find subscription and pay-as-you-go plans for large and ongoing campaigns.
