What do you all use / recommend for mailing list software?<p>I help a local charity with their website, and we have a number of Google Groups (with our domain) for our internal communication (no external marketing). However, the email will frequently be classed as spam by Yahoo and Outlook. I've been in touch with their postmaster teams, and each time they will first blame Google and then tweak their spam filters, which works for a week and then our list email goes to spam again.<p>I wouldn't be surprised to learn that it being filtered as spam due to the Google Group footer - which can't be disabled for external email addresses.<p>I'm fed up with the whack-a-mole, and wondering what alternatives there are? I just need a central email address that members can email, and that then be sent out to the members.
In case anyone finds this through search in future, I've just received this from the Yahoo postmaster team:<p>> Our engineering team has looked into this and you'll need to have your users mark the mail and not spam. We don't have anything else to suggest.<p>It is unbelievably frustrating. I'm giving up on using Google Groups (which is perhaps what Yahoo and Microsoft want).
Is this really a question of software vs deliverability setup? Did you validate all the SPF, DKIM, and DMARC stuff already?<p>If your email group is for internal use only, can you set it up at the level of your mail server instead? It should be able to just copy all the messages to the other users instead of sending it over the internet. eg for Google orgs, <a href="https://support.google.com/a/answer/9400082?hl=en" rel="nofollow">https://support.google.com/a/answer/9400082?hl=en</a>
