>>Are you getting any error messages from Yahoo?
Just the typical EMAIL DEFERRED one.
>>Is your email still being accepted and delivered but going to the junk folder >>instead of the inbox?
Still going into the inbox but delivery dropped down to like 30-50% over the last 10 days. I know many others who also mail Yahoo who have experienced the same issue. This isnt related to the SpamHaus incident, we've confirmed this isnt the case. I'm thinking something changed with their filters?
>>Have you previously completed the Yahoo email bulk senders request
These are whitelisted IPs, have been for the last 2 years. Our reputation was fine until 10 days ago. We've backed out the recent data we added up to a week before the problems began.
>>What do you mean by different templates? Personalizing the emails
>>with greeting such as "Hello $firstname," ?
We mail 3rd party offers to our optins, these are people requesting to receive specific verticals. So lets say we send an offer to those who check a box on our site saying "I want to receive info on work at home jobs", we will send them that particular offer. But if we send that offer again in 2 weeks, we wont change the text inside, we'll mail it as it was.
>>Is the ESP seeing a drop in delivery rates across all of their lists or just yours?
They claim everybody else is fine but I have my doubts, since everyone I talk to has said something changed for them in the past 10 days as well.
>>How many IP addresses are sending the email lists?
1 IP address. Whats very odd is we have 2 domains sharing that IP. Domain #1 mailing list #1 gets great delivery (no issues). Domain #2 mailing list #2 has issues.
One thing we noticed list #1 has < 100,000 subscribers from Yahoo, and list #2 has > 200,000. Perhaps theres been a limit on the amount/volume we can send, so thinking of segmenting the data into 100K slices and trying that?
I assumed Yahoo bases reputation on IP alone but apparently domain is more important?
>>Is it possible to spread the email sending across more IP addresses with >>known good reputations?
Not really, this is an ESP and we have been using the domains for 2 years, this is why Im surprised, youd think Yahoo would see the fact we've been here awhile and playing by the rules.
>>I separate my mail to Yahoo into two main groups, a pool of servers that
>>handles email from end users one at a time, and a pool of servers that >>handles email lists and other bulk mailings.
Are there any links to threads you can share that show what steps to take in order to mail to Yahoo directly? I'd like to try mailing on my own server in house, but have heard its very hard. Any help would be appreciated.
