I was recently confronted with the task of sending out a mass mailing. Now,
there is nothing terribly exciting about that, but due to the delicate nature
of the mailing, I had to track responses to the mailing itself: how many
bounces, who answered, etc. (I know, I know: that kind of stuff is usually a
secretary’s job – at best –, but this time I was the secretary.) The message
was phrased in such a way as that recipients would be very interested in
acknowledging its reception. A piece of cake, you’d say, and so did I, so I
enjoyed a piece supplied by the best pattissier in town. The
Pralinentorte you see here has enough calories to nourish a small country
for about a week, and it is truly scrumptious – I digress.
This mass mailing wasn’t directed at housewives (no offense to housewives) but
to businesses – most of them small – with whom the organization I did this
for kept regular e-mail contact, or so I thought. In said mass-mailing, most
of the addressees the mail went to represented smallish organizations who have
their e-mail hosted at one of the sundry free-mailers or local ISPs. 14% of
the messages failed at the first attempt. Of those, 37% bounced with a 55x
code indicating target mailbox is over quota or the accepting mail server
can’t relay onwards. 19% of the addresses where rejected (no such user), and
44% were unroutable (e.g. because the domain name no longer existed). After 24
hours, 22% of the messages hadn’t yet been delivered (we kept getting warnings
about non-delivery). Of the messages that got through unharmed, only 40% were
reacted upon within 36 hours. Larger organizations typically maintain their
own e-mail infrastructure, and they have system administrators who (sometimes)
know their job. Experience shows that there is seldom a problem to get an
e-mail to such an organization. (Whether it is then read by the correct party
is a completely different topic: I’m simply talking about successful SMTP
delivery at this point.) Small joints or one-man-shows don’t have that luxury,
can’t afford to have it, and don’t need it, because there are dozens if not
hundreds of Internet Service Providers who provide that service for a
typically very small amount of money. The operative word here is provide. Do
they really provide service? E-mail still isn’t a piece of cake.
