It’s easy to find what you were talking about with Slack, and the documentation is also easy. The threading is awesome and you can find records immediately. It is cool that it keeps all the communication in one place and you can easily search it.
MailButler is a great plugin for a mail client. It’s good for read receipts and gives you interesting analytics. We can see the performance of our pitches, when they read it and what was more effective. We can get insights based on the timing of the email that has been opened.
