I now have the (current) definitive solution to this.
Our mail server, SendGrid, offers a free plan in which we have a shared IP with other users. There is little we can do to avoid this IP from occasionally popping up on spam radars. The cheapest plan in wich we get a dedicated IP costs £80/month… so we need to grow first!
When their IPs are blocked SendGrid actively want to know about it, and will take active steps to have the IP we are using delisted for the ‘blacklist’. This generally solves our problems for a time until some other user of the shared IP gets the IP blacklisted again.
At our current rate of email usage there is little we can do about this, apart from change mail providers. However there is not a better solution if we wish to continue to explore whitelabelling our emails (which we do). For the purposes of whitelabelling I feel this is a fair tradeoff.
Since this is affecting only emails CCed to Food Hubs and only at some times I would like to propose we live with this, actively managing our blocked emails, for the time being.
What OFN UK Will Do
Regularly monitor SendGrid for blocked mail. If any of this mail is important communication to a producer we will ensure it is forwarded on.
What We All Need To Do
- Be vigilant with our spam filters to ensure that no OFN emails hit our junk folders.
- Notify us if you don’t receive any mail that you know you should have. This will mean an IP is being blocked again and we need to contact SendGrid
How does that sound for the time being?
