posted today in: LED Digest 2216: More on Open Rates and Bounces From: Charles Gartrell Subject: Email delivery rates Date: Wednesday August 2, 2006 We had noticed this issue a while back, even for smaller lists (few hundreds), with large numbers of bounce-backs and what have you. This coupled with the GoodMail systems did not not bode well for our customers (which generally operate small to modest size mail lists). In a few cases with a list of around 9000 we even saw delivery ratios at less than 10%. We did not have a bunch of happy campers to say the least as result. Since delivery and open rates are for the most part more important to our customers than speed, we tried something a bit different. First we dropped use of our mail list software and developed a custom application. This new system (at least to us) does the following - sends both HTML and text messages to each address, customizes each message with the subscribers name and email address, and sends no more than 50 messages per hour (not exactly true - it sends messages seperated by quarter of a second between each for a group of no more than 50 addresses) until the entire list is completed. Now admitedly this is (very) slow but it works - bounce backs are very small, bad addresses are few and open rates are very good (we have one list over 90%). Is this a universal solution? Nope... this approach is only effective for small to modest lists (< 15000 or so) but it does work and our customers are happy again. How long this will work is another matter - major ISPs will muddy the waters again I'm sure... Comments (0)
