Productivity boosting add-on for Apple Mail.
Pro Allows users to connect to different cloud services to save emails and attachments
MailButler adds extra cloud integrations to the default Apple Mail. You can only save attachments to iCloud by default, but with MailButler, you can add other cloud services which can be used for storage.
Pro Schedule emails to be sent later
With MailButler I can compose messages on some day or even during the night and let it automatically deliver the same message on a particular date and time in the future.
Pro No need to deal with third-party email options
MailButler is simply a collection of plugins which increase the power of Apple Mail. It's still working on top of Apple Mail, so there's no need to install and configure a third-party email client.
Pro Email tracking
With this MailButler feature, you always know if the recipient has actually opened your email.
Pro Supports creating todos from emails
You can transform an email into a task with reminder function. This function can be used with Todo apps like Wunderlist or Todoist.
Pro Supports snoozing emails
Keeps your Inbox clean by temporarily putting "snoozed" emails to a snooze folder and making them reappear in your inbox folder at a specific time.
Con Pricing is a bit confusing
The way MailButler is priced may be a bit confusing to some users. It has a free tier which allows you to use up to 20 actions a month (basically meaning you can use MailButler's features 20 times in a month). However, in order to obtain more uses, you need to pay a subscription fee of $9/month.
