Pointofmail analyzes your tracking data and provides real-time reporting. 04 of 05 Confimax What We Like Lets you send mail a few different ways. Two plans are available to pick from. What We Don't Like Plug-in doesn't work with every email program. There isn't a free option. The cheaper plan doesn't email the results to you. Confimax certified email service makes it easy to receive return receipts as soon as the recipient opens a message—assuming both accounts are compatible with the service—which not all of them are. Of those that are compatible, some have limitations including AOL mail and Lotus Notes. Check the compatibility of Confimax with your email service before proceeding. 05 of 05 DidTheyReadIt What We Like Provides easy login via social media sites. Several options can be customized. Works with a variety of email clients. Four plans are available. The free plan never expires. Lets you send mail from their website. What We Don't Like Free plan is limited to 10 messages per month. Doesn't support choosing a different email account to send from. DidTheyReadIt makes it easy to know if and when an email you sent is opened, assuming the recipient opens it while online. The service is easy to use. However, DidTheyReadIt is problematic because recipients have no idea their interactions with the emails are recorded, and there is no way for them to opt-out of DidTheyReadIt return receipts. With today's heightened interest in privacy, this may be a deal-breaker for some companies.
