Mailing lists are just like anything else in this world - they need
to be maintained and updated regularly, otherwise they become less effective.
Here is something to think about - the average life span of an e-mail account
is anywhere between 6 months to 2 years. People switch work, change their
providers, websites shut down regularly, companies go out of business. If
you purchased a mailing list a year ago with 1000 active addresses, expect
5 - 15% of them to be "dead" by now.
If you gather email addresses yourself from
your website, you probably noticed that a large chunk of them are either completely
meaningless (such as kate!@$aol,com) or contain errors and typos (such as
htomail instead of hotmail or .ocm instead of .com).
As a marketer, you need to get rid of "dead" e-mails from your
existing lists and prevent invalid e-mails from making it to your new mailing
lists for two reasons. The first reason is the cost of bandwidth - why pay
for e-mails that will never be looked at? The second reason is statistics
garbling - invalid e-mails lower your ROI values and mislead you about you
campaign effectiveness.
Atomic
Mail Verifier (AMV) is a software that can do all these things for you
for less then $40. Best of all, there is a free trial version that lets you
get familiar with it before you pay any money. To get rid of the bad ("dead")
e-mail addresses, Atomic Mail Verifier goes through these three steps:
- It looks through your
list and checks for bad syntax (addresses like bill#yahoo.com);
- Then AMV looks for
non-existing domains (such as imadeitup.com);
- Finally, AMV connect
to all valid domains and tests whether the actual e-mail address is valid
and active. The final step requires SMTP connection and takes quite a bit
of time. So if you have tens of thousands of addresses, you might want to
do this overnight or split your mailing list into smaller parts to spread
the job evenly over a period of time.
Importantly, Atomic Mail Verifier is fully integrated with other mass-mailing
software tools form AtomPark Software. So you can use our extracting software
to gather email addresses, pass them through Atomic Mail Verifier and send
your message to the remaining active addresses with Atomic Mail Sender. The
whole operation takes only about an hour and you will start getting the results
immediately.
