SMTPing

I recently had the chance to use the email validation service, and I must say, so far so good! The validation process was incredibly fast and accurate, allowing me to clean up my email lists efficiently. The results were precise, which significantly improved my confidence in my email outreach efforts.

Moreover, I appreciate that they also offer some email warm-up services. It would be fantastic to see these options available on AppSumo soon, as they would further enhance the overall email management experience.

A tabular representation of the validation results would be an excellent addition as well, making it easier to analyze the data at a glance. Overall, I'm impressed with the service and look forward to future enhancements!
