Hi there.

If you’ve gotten this far in the post, I want to say thank you.

When I wrote this post, it was mostly as an inside joke. My friend and I went back and forth using the above formulas, the subject line being arbitrary except for the fact that it signaled a new conversation.

Surprisingly, this post has become one of the most popular posts on the blog. Getting in touch with someone is such a simple thing. But it seems like all of us need help finding the right words to say.

So I wanted to provide a little more help to those of you who googled “email subject lines” and ended up here.

Here are two articles that I found helpful in getting in touch with others, whether to reconnect, ask for advice, or offer condolences.

The Fastest Way to Write

Suppose you landed here on this post looking for how to compose an email subject line for a professional email instead of a personal one?

There is also another cool way I’ve found to compose letters and articles when you need a little push to get the words flowing.

Jasper, formerly known as Jarvis, is an AI program that helps you write everything from blog posts to cold emails to social media captions.

I recently signed up for a free trial of Jasper and played around with its Email Subject Line template. Here’s what happened:

I opened up the Email Subject Lines template:

I typed in my info in the prompts to the left:

I generated the AI content a couple of times:

See? The output is simple. But sometimes we writers overthink things that should be simple, like email subject lines.

I also like the idea that any of these subject lines could have been brainstormed by a marketing team in a meeting—which would have wasted everyone’s time—OR, they could have been generated within 10-15 seconds of pulling up the template page. Since so many of us are a marketing team of one these days, an AI writer like Jasper could save us time on menial tasks so we can spend time on more important things.

I have to say that the writer in me is a little unnerved by Jasper. At first, I thought, “is it going to take my job and livelihood?” But I think what it does is just save you the time of searching for an answer on Google.

In case you are wondering, yes—I may get a small commission if you sign up for Jasper. But note that I approached them for the pleasure of doing so because I had tested out this product and thought it was pretty cool.

  1. ‘Hey’, ‘Hi’, ‘Hello’, and ‘What’s up’ doesn’t seem to be good subject lines in my opinion, because it’s almost like saying hi in the subject line and leaving your email body empty, if saying a hello is all you want to say.
    I want to drop a mail to an old colleague, just to pass him my email ID which I couldn’t do in person. There’s very little scope for a long conversation, just need to share pleasantries. What could be few Subject lines I can possibly use?? (‘Greetings!’ seem to be one.)
