So I have been using email verification for around 5 years and been called upon by several verification companies to evolve their product with shifting technology whilst still remaining valid with legacy technology. It is first really important to realise there are 3.8 billion ‘active’ emails in the world and several times more inactive, temporary and bot generated ones. In addition these emails belong to several thousand email providers ranging for up to date email service technology to legacy servers that have been left to rot 25 years ago yet still active (and let’s not forget the tens of thousand email servers that are now redundant and still not known to be, even by the likes of google and Microsoft. Speaking of Google even they do not have a 100% certainty to which email addresses they service are good or bad, and they own them! So with all these in mind there is no service on the market today that can validate 100% of all seen email addresses 100% of the time and until quantum processors are optimised in global servers; there never will be. So what you need to be looking for is which service can get you closest to ‘perfection’ about 2 years ago I rigorously tested Bouncer with over 15 million email addresses that had already been manually and digitally verified against 5 other well know and respected validation companies which were briteverify (now know as validity) kickbox, neverbounce, emailvalidation and zerobounce. Now all of these companies had a minimum accuracy of 97% which they all lived up to 90% of the time however kickbox and bouncer where the leading 2 with both reaching accuracy of 99.7% in most batches (of 15 time 1 million emails) but with bouncer was more consistant, 11 of the batches hit accuracies of between 99.7 and 99.8% where as kickbox only managed 9 batches within the range. Thought 100% is common on smaller batch sizes, one should not be disheartened as a 0.3% bounce rate is outstanding in today’s market of an average of 0.7% On the point of false negatives (valid emails being flagged as invalid) well the the same accuracy can be considered here too with bouncer falsely invalidating around 0.3% but this is a minuscule price to pay to keep your deliver rate in the green
