Email Marketing Inspiration: September 2018


Don’t you love a good subject line? We sure do.

This month’s email marketing inspiration roundup is brought to you by fantastic subject lines. We had so many land in our inbox this month – it fills us with the email warm and fuzzies.

Let us know what you think of these emails or share your favorites! Leave a comment below or hit us up on Facebook and Twitter. We’d love to hear from you.

Not Your Average Nut Butter Email (RXBAR)

RXBAR usually sends great, simply designed emails. The clever subject line on this email is what landed it on our favorites list this month.

The subject line, “This is not another email about protein bars,” had us clicking in seconds. Wait, RXBAR makes more than just protein bars? We had no idea! What else do they make?!

OK, so maybe not everyone gets this excited about nut butter, but we thought it was a clever way to engage the subscriber. The preheader text pairs perfectly, too. And as we mentioned, RXBAR emails always look sleek.

Death Star-Sized Outage (MeUndies)

Earlier this month, MeUndies announced a Star Wars line that sent underwear fanatics into a frenzy. The new print was so popular that it crashed the MeUndies site.

Shortly after the outage, MeUndies sent out a follow up with the subject line, “The Death Star Crashed Our Site…But We Fixed It.”

The subject line was a great way to admit a mistake, but also engage the subscriber to snag the high-demand undies. The email GIF also makes great use of showing off the special glow-in-the-dark pattern.

Smells Like…A Great Email (InVision App)

InVision rolled out a new guide last month that outlines the design sprint process and how it can help enterprise teams. Yes, this is an email roundup post, but we wanted to give props to a beautifully designed guide, as well.

But it wasn’t the design that had us clicking on this email – it was the subject line. The email, sent by Clark from InVision (nice personal touch), referenced a rather popular song from the 90s grunge days. The subject line read, “Smells Like Team Sprint.”

It made us chuckle, and of course, we had to click through. InVision also always has great graphics to complement their email copy.

On-Point Rebranding Announcement (Mint)

The personal finance service Mint announced some branding changes and new features last month and we thought their email announcement was on-point.

The message, which has simple design and copy, does a great job announcing the rebranding while also piquing our interest. There’s more to come, Mint says, and now we’ll be checking our inbox with anticipation.
