19% Of Email Addresses Provided in Free Offers Are Bogus

Not long ago i did a study for a customer who acquired a sizable number of e-mails that they collected issues free-sweepstakes form. Entrants were asked to enter their name and their email address for an opportunity to succeed a daily prize respected at $1, 000. Around the entry form the online marketer did basic JavaScript acceptance tests on each address entered by the consumer and this naturally stored out a lot of improperly formatted e-mail address from being written for their database. However, the internet marketer did not do an outbound verification e-mail to their customer to verify the accuracy of the address that was moved into by the entrant or did they do use a real-time e-mail address checker to verify the addresses. check if email is real

Service Objects has a corporate client that gave us approximately a hundred and twenty, 000 email addresses from various campaigns and on various dates this summer. Every single address was processed through our email validation service. Each address was checked out for syntax, domain-level abilities and mailbox-level validity; additional checks for vulgar and bogus addresses were performed.

At first glance the addresses looked OK. That they were properly formatted and their domains (right aspect of the address) generally belonged to the top e-mail providers like googlemail, Yahoo, Hotmail and others. However using email approval tools, we determined that 18. 7 percent (22, 700 out of one hundred twenty, 000) had mailbox level errors. These addresses are undeliverable because the mail box aspect (the left-side of the address) is no longer a valid working mailbox.

An example of one of these details is: cgommer @ cox. net. The address has good syntax, a working MX record, a valid SMTP server however the post office box aspect (cgommer) is incorrect according to cox. net. Perhaps this entrant made up this address? Most likely she moved ISPs? Presently there is absolutely no way for us to find out with fully accuracy. It was a bad address and should have been marked in their database as so.

So why valid email addresses subject: Marketers who look to re-connect with clients need valid working addresses. Email companies like Constant Call and MailChimp have guidelines in which they seek a maximum allowed bounce-back rate of only five per cent. If your bounce-rate is actually high you will be banned from posting with their service. Funds to weed-out poor quality lists and reduce weight prove mail servers.

What you do about this: Internet marketers seeking to improve their email quality should take the following actions:

use JavaScript based email affirmation
use a hosted email validation tool
send a confirmation email to check users identity
should occasionally re-validate the list preceding to any bulk mailbox campaign
