I became enthusiastic about using mailers after joining Your Viral List and reading the Top 25 converting sites and seeing how quickly the site grew. So, I thought I'd do testing on my own because I wanted to find out "the rest of the story"... you know... like what's the CTR? and what is the ratio of how many messages to read versus how many views delivered?
Here is what I found as an average for 2 weeks (each using the free account):
List Surfing - 4% - read 3:1
10x mailer - 3% - read 3:1
Marketing Checkpoint - 2.5% - read 1.5:1
List Impact - 2.5% - read 4:1
List Jumper - 2% - read 2:1
Traffic Bonus - 2% - read 3:1
List Joe - 2% - read 4:1
List Bonus - 1.5% - read 2:1
Bweeble - 1.5% - read 4:1
#1ProfitRing - 0.8% - read 6:1
WebBizInsider - 0.6% - read 6:1
Herculist - too low to mention
I can view about 500 pages an hour.
My end result was that I spent 2 hours earning credits for 1 subscriber; which, I don't think is terrible for this test, but obviously needs improvement! If paying 0.01 per click, that would be $8/subscriber.
I'll weed out the ones that take a lot of work for low CTR, try a few others, and change my landing pages to see if I can get better results. Though I haven't lost interest in mailers, I can certainly see why it'll be necessary to pay for some advertising if I want to grow my business into something that will support me this year!
