- In the past year or two, email service providers have all gotten significantly more aggressive at filtering spam.
- Even a legitimate company sending a lot of user-requested email risks being flagged as a spammer, for reasons as simple as a high send rate.
- There are a multitude of different whitelists and policies that control email delivery at ISPs. There is no standard bounce message format.
- Despite that, you have to act on bounce messages. Dogster collects all bounces into a database, presumably to help employees find and act upon the most critical email blocks. These bounces might also be used to trigger automated responses, such as a temporary slowdown in email to a particular mailhost.
- Some companies are appearing to serve this niche. One service is delivery-testing: a company gets email accounts at a bunch of ISPs and lets you know which ones are rejecting your emails. Others offer a mail-sending API, where you use their (presumably ubiquitously whitelisted) servers to give your emails that extra smidge of legitimacy. These services appear to be expensive and nonstandardized so expect to do a lot of work either way.
Quote: "While I used to be disgusted at AOL's and Yahoo's plan to start charging email senders to deliver their messages, considering the money we have to spend to stay in their good graces, we would now prefer to simply pay in advance for our emails to be delivered and know that they will."
