We have made a change to how we handle the sending of recommended searches. previously, each and every agent-created recommended search had to be implicitly opted-into by the recipient. While this was following the letter of the law, this was causing a lot of hassles. We have relaxed these rules and now will send recommended search subscription emails to your signed up leads with no opt-in required.
We are also working on a more comprehensive solution that will give agents more control over how these emails get sent out. If agents choose to spam recipients they will be hurting their own domain's email spam reputation (not ours). This project involves making it so agents on our premium plan can send emails from the relevant website's domain, complete with return-path support. We're hoping to get this project completed in the next few weeks.
