Introducing our upgraded subject line analyzer, now with automatic subject line generation.
Oh, the subject line. So simple - just one line - and, yet, why is it so hard to come up with a few versions for a Message Test?!
Before you make another burnt offering to the muses, we've got news for you! Motiva's Subject Line Analyzer now automatically generates subject line versions for you with the click of a button.

Start by writing your initial subject line, whether it's for a newsletter, event invite or product announcement, and then click the "Analyze" button next to the subject field.

Once our analyzer evaluates your subject line, you'll see a new option to "Generate Variations" in the top right corner. Click the button and a few second later, 5 new variations appear that you can use in a Message Test.

And with Motiva's multivariate Message Testing capabilities, you can test more than one to see which works best for your audience.
Don't like any of the new variations? Tweak your original subject line using the feedback from these new variations and try again to get new variations.
Then use Motiva's analyzer to get deeper insights. Our subject line analyzer uses natural language processing — a subset of artificial intelligence — to evaluate and grade for Clarity, Spelling, Spam, Engagement, and Concision, as well as an analysis of Tone and Readability.
This breakdown will give you an idea of how your prospect will perceive your subject line, both with letter grades A through F, and a graphical representation.
For example, does the tone match your brand’s voice? If you're experimenting with a new tone, what audience segment might resonate with it? Any spelling mistakes? How likely is it to be considered spam, either by the email service provider or your prospect?
One way to leverage our subject line analyzer would be to take a proven subject line (one that exceeded your benchmarks) and use it as a guide for future message test experiments. Does your proposed subject line’s analysis closely match the previously successful one?
Also, be sure to check the Details button for each of the categories it analyzes. The tips provided will change based on the subject line you’ve entered, so the pointers provided will be specific to the subject line you're analyzing.

For instance, in the example shown above, it suggests using simpler words. For spelling, if you use Drop Caps At The Beginning Of Each Word, it will suggest removing the unnecessary capital letters to reduce the likelihood of your message being flagged as spam.
If your Engagement grade is failing (or you just want to give it a boost), try restructuring your subject line, so it starts with “How to,” or rephrase it as a question. These are more likely to pique the interest of your prospect and get them to engage.
We’ve also been tweaking the summary paragraphs at the bottom of each analysis. Now you’ll get more detailed insights into how your prospect might respond, along with suggestions for improvement.

If everything looks good, send it!
