Mailing Vertical

I think assuming data from “vertical x” will respond to offers in the same vertical is a mistake in and of itself. The thing to do IMO is try a high clicker type of offer like coupons, zip/email submits – something well branded that will illicit that click you’re looking for. Load up something completely different and give it a shot; doesn’t sound like you have much to lose rev wise at least!

What Emailing Business is Mainly About

Emailing business is mainly about

1. data (good or at least fresh)
2. ips (and maintaining reputation – see #1) [several for Big4 Broadband / 1 a day for GI]
3. MTA supporting current standards (DKIM, SPF, DMARC, ip throttle, message throttle, back offs, etc…)
4. domains (for infrastructure – froms, clicks, rdns, fbl, etc…) some of this doesn’t apply to GI but to Big4 Broadband

As for offers, subjects, format, servers, networks – DO 1-4 first !
The rest is just tweaking and optimizing.
These are also important but without 1-4, it will be an uphill battle.

Even if you have the dumbest subjects in ugly broken english text format
promoting a used condom with a flaky network or advertiser, YOU WILL get opens and clicks
and maybe 1 convert if 1-4 is in place.
