Mail on the Mac does not have a built-in scheduler. That means you can only send email messages with a click– either immediately, or later after saving a draft, but you have to do the click manually. Here’s a way to automate email scheduling according to time and date so you can send messages in the future, unattended.
Send. It. Later.
My two favorite Mail plugins are Spam Sieve because it captures spam better than Apple’s built-in Junk Mail filter, and SendLater. All SendLater does is send any email message you want, but at the exact date and time you want to send it. That’s right. You control the date and time the message is sent from your Mac.
This kind of flexibility is valuable. Messages get sent at some point in the future even when you’re not around. That means you can reply to or send a message early in the evening or morning, but have it sent later; while you’re sleeping or having dinner out.
Installing and using SendLater is about as Mac-like as a Mail plugin can be. There’s nothing to setup or configure. Instead of clicking the Send button, click the Send Later button instead (it displays just to the right of the Send button).
When you click the Send Later button Mail drops down a scheduler which gives you a way to schedule when the email message will be sent.
Select Special Date, Time Distance (number of minutes or hours from now), or a specific Time and Date.
Click the Send Later button in the pop-down window and SendLater schedules the email message to be sent according to the time, date, schedule you set.
I’ve been using SendLater for a few years and it has become an indispensable way to send messages or reply to messages on my schedule, but have the email sent on a schedule I choose.
The only gotcha is that SendLater, like the popular Spam Sieve, is a Mail plugin and when Apple updates OS X sometimes the plugins won’t load in Mail. That’s easily fixed with MailPLuginFix, a free utility which fixes Spam Sieve after an OS X Mail update, too.
As valuable as SendLater can be– anything that lets a Mac users send an email message according to a schedule is a special, must-have utility– it appears as if the utility is being rolled into a new product called MailButler which melds together customized email signatures, email scheduling, storing attachments to a cloud service, and other features– for a monthly price.
It looks like subscription software is here to stay.
