All other ISPs (Google, AOL, Hotmail) are fantastic, hitting 98-100% in the inbox. Yahoo is very random, and lately our deliverability has dropped drastically. All IPs are senders certified by Return Path and supposedly that automatically whitelists our IPs and allows us to send as many emails as we want (from what my boss says).

Do I bother with applying to Yahoo's bulk sender form?

I run every email campaign through:

  1. SpamAssassin (Excellent Scores)
  2. Test Accounts (for test deliverability)
  3. Old school HTML format

I'm running out of ideas and I'm starting to be in the hot seat and I am very fearful for my job position.

If you can offer any wise words i will be very grateful. Thank you in advance.

First, I'd confirm that "supposedly". ;)

Also, I would try sending a small email list from your local computer via SendGrid or Amazon SES. Just to double-confirm it is not your content causing the problem.

Review, in detail, Yahoo's postmaster FAQ.

And, definitely fill out the Yahoo Bulk Sender form.

Just a final thought too - if the lists you're sending to have your email and/or domain blocked in their personal preferences - there is nothing you can do about that.

Here's what I'd do:

  • Check if the SPF records are configured as they should.
  • Enable DKIM/DomainKeys for the domains.
  • Check if the server is in any blacklist
  • Send an email from the server to this address: check-auth@verifier.port25.com (they will reply with an extensive nice report)

If you have all of this properly configured, try the Yahoo bulk email form.

Also, check whether the IP address of your outgoing mail (smtp) server resolves back (reverse dns lookup) correctly.

In addition to the bulk email form (do it), there's a Yahoo! customer care concierge service (no kidding) which may be able to assist. Try the bulk email form first.

In the past, I've resorted to contacting Yahoo execs directly (first.last@cc.yahoo-inc.com usually), but really reserve that for particularly egregious issues. Last time I tried that (a couple of CEOs ago) I got hooked up with the concierge.

Getting mail into Yahoo can be a real pain, even if you're fully legitimate.

If these IPs are certified by Return Path, ask them what you can do. They are very helpful in this sort of situation.

  1. Add an SPF record in DNS

  2. Add a PTR record in DNS

Adding PTR record is not recommended for modern email delivery - it exposes domain for IP, increasing possible intrusion for web domain.
