Mailbutler is a plug-in for Apple's macOS Mail client that adds some very helpful features that I use regularly. Most notably, I use it to add a delay to the sending of emails (currently ten seconds) and to be able to determine whether an email has been opened by its recipient(s). Mailbutler offers a free plan called “Mailbutler Essential”. If you are using the free 'Mailbutler Essential' plan all outgoing emails will include a Mailbutler watermark at the bottom of the email. On the Essential plan, it is not possible for you to remove the watermark. The watermark will be automatically added to the email when sending.
