Many validation companies do assessing where it assesses certain steps if the email exchange is set up correctly. So as to understand verification and to select the perfect company, it is important to search for clear signals of authentication as most verification businesses miss many steps so as to save money.
Social networks (the wrong way)
Consult your email list cleaning business how they do confirmation. Get them to be specific. Ask them if they do email list cleaning free of social networks. For some time, email marketers asked that emails be patched against social networking email accounts.
Appending (the wrong way)
Request the email list Verification agency should they append date/time stamp emails which were verified during a particular date appointment. For instance, to save money, many confirmation businesses saves the time and date stamp of when the email was confirmed.
Scoring (the wrong way)
Much like appending and social networking above combined, many confirmation companies will give a technical term of grading as their reporting feature. They offer you the email on a scale of 0 – 10 (0 as good and 10 as awful).
SMTP Link (the right way)
For an email to be verified properly, without skipping steps, it needs to be delivered. ISP's have particular thresholds to allow quite a few emails in from an IP range. Yahoo may allow only 3,000 from an IP per 24 hours or Gmail 300. You may contact Bounceless.io for Email Address Verification & Email List Validation services.
Real-time (the right away)
With an SMTP connection, one can do real-time reporting. To be able to get the most bang for your buck, the email must be assessed in real time which means as the listing is draining, the machine is sending an SMTP signal.
