135+ Email Content Ideas to Fill Your Marketing Calendar in September

To create any email campaign, you should consider a lot of factors: come up with a creative design, prepare offers, build the right segments, configure product recommendations, etc. September emails are no exception.

When the back-to-school season is over but it's still too early to start with Thanksgiving, marketers need to look for other opportunities to connect with customers and keep the conversation going. And although September may look poor in email content ideas, there is actually plenty of reasons to reach out.

Good causes to make your recipients’ inbox happy in September:

  • Customers’ birthday;
  • Your company’s birthday;
  • International and local holidays;
  • Anniversaries;
  • Sports events, like championships, marathons, races, etc.;
  • Birthdays of famous people;
  • Invention dates;
  • Historical events;
  • Festivals and parades.

Email Content Ideas

There are different kinds of events: international, national, local, typical of a particular region or continent. An international brand should know that not all of them are celebrated around the world: people in China may not know about La Tomatina - a food fight festival organized in Spain every year. On the other hand, not many Spanish are aware of Dragon Boat Festival held in China annually over 2,000 years.

However, even if your audience isn’t familiar with this or that event, it won’t hurt if you introduce them to your subscribers. Just make sure you pick up the right email marketing content applicable to your business. For example:

  • Stylish celebrities’ birthdays deserve a mention in campaigns by clothing, jewellery, perfume, or beauty companies;
  • World championships, motor racing, and different tournaments can be a good reason for sports gear, nutrition supplement, gym equipment and even insurance companies to get in touch;
  • International and national coffee, bakery, chocolate and any other sweet days look as if they were specially designed for coffee shops, confectioneries and bakery magazines.
  • Any event dedicated to eco-friendly activities is a good opportunity to remind your customers that you contribute to nature conservation as well (of course, in case you really do).
  • If there is a special day dedicated to the kind of product or service you provide, don’t miss a chance to come up with a specially-designed campaign.
  • Your customers’ birthday is an event you simply can’t leave unnoticed. Pleasant gifts, warm wishes and festive images are more than welcome.
  • Your company’s birthday also makes a good email marketing idea. Tell your story, boast a bit of your recent achievements, introduce new products or reveal plans for the future - it’s your birthday and it’s up to you to pick up the content you want to share.

Day Holidays and Events to Look for in September 2021

And now let's move from general calendar to particular September email ideas. You definitely don't need to use all of them, but I'm sure you'll find in the list the event resonating with your brand. And even if Eat an Extra Dessert Day or National Milkshake Day are local holidays, so what? A few people would refuse to celebrate whatever that involves eating sweets or drinking milkshakes. Take a look at other email marketing content ideas to include in your welcome campaigns, reactivation emails or newsletters, and take your email marketing to a whole new level.
