These 4th of July email subject lines will help your online store have successful campaigns, since the research is based on real, high-converting emails.

But we know that researching these by yourself can take a lot of time. Which is why we did it for you—40+ high-converting 4th of July subject lines that you can use today.

(If you’re still unsure how to proceed, read about how to craft the best email subject lines.)

Perhaps because it falls right near the middle of summer, the 4th of July (Independence Day) is a great patriotic celebration.

Compared to other countries, where it can be a more somber affair, the American Independence Day is a time for fun, sun, barbecues and cocktails.

People plan to spend a good amount of time (and money) on having fun–whether that’s a simple barbecue with friends or a longer period of time near the beach.

Beware, therefore, that it isn’t necessary to use patriotic themes (US flag, historical figures, etc.).

Instead, focus on the fun aspect and make sure the products you’re selling are aimed at helping people have a fun time for their Independence Day celebrations.
