Changing the sending domain and the IP addresses won't help at all if you haven't solved the underlying issue, you're just kicking the deliverability can down the road. Is the domain using DMARC to prevent spoofing, and what's the policy? Are all emails signed with DKIM? What does Google Postmaster Tools show for IP reputation, domain reputation, and complaint rates? How is the customer acquiring their list? Are they using double opt-in? When an email goes to the spam folder, does Gmail show a banner saying why it was sent to spam? If so, what's the banner say?
Gmail is very good at spam filtering, so your best bet is to assume there's a problem with the sender's practices and work backwards from there. ________________________________ From: mailop <mailop-boun...@mailop.org> on behalf of Jan Schapmans <jan.schapm...@selligent.com> Sent: Wednesday, August 22, 2018 8:25:46 AM To: mailop@mailop.org Subject: [mailop] Gmail - Anybody out there from Gmail, willing to assist with strange reputation issue Dear Gmail, we are having for a UK customer an inboxing problem with Gmail and only Gmail. Over a month ago we’ve changed their ip addresses, changed their sending domains, started warming up again, all was good until a few week ago: the reputation of ip’s & domains are suffering again and open rates dropped again. [cid:image001.png@01D43A3D.288C0CB0] We now * send them from a subdomain from our own corporate domain * target only the most recent engaged Gmail users (last 10 days) * exclude anybody who is only just clicking on the unsubscribe link (even without fully completing the unsubscribe process) * monitor the complaints (list-unsubscribes) and make sure they are honoured. Seems like we are missing something, but can’t pinpoint what it is. We have to admit at first there was something wrong with their setup and complaints & unsubscribes weren’t processed properly. Can it be that reputation is catching up after a while? Even on a new warmed up subdomain? Since last week results are somewhat better & stabilizing around 9% open rate but all other domains are at 20% or higher. (even Gmail was higher at some point) [cid:image002.png@01D43A3D.288C0CB0] I hope somebody from Gmail can point us to something we are missing, but I’ rather have them confirm we are doing ok now and rates will go up :) Kind regards, - - - - - JAN SCHAPMANS DIRECTOR DELIVERABILITY SERVICES mobile +32 498 93 29 65 email jan.schapm...@selligent.com SELLIGENT MARKETING CLOUD CONSUMER-FIRST MARKETING www.selligent.com<http://www.selligent.com/> The information contained in this communication is confidential and is only for the use of the intended addressee.
