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

To create an email campaign, you should consider a lot of factors: come up with a creative template, prepare a list of products, build the right segments, etc. Creating your own event schedule filled with original content is also an important factor that will help you stand out among other companies and enhance the efficiency of your campaigns.

Each month brings numerous awesome opportunities to connect with your customers. However, to be ahead of the game, make sure you plan your content calendar in advance. A last-minute publication way behind the event won’t win you much customers’ love: your campaigns should be relevant and up to date.

Good reason to make your recipients’ inbox happy:

  • 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.

How to Use and Who Can Do It

There are different kinds of events: international, national, local, typical of a particular region or continent. 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 cases 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.

International Sushi Day in an email campaign

  • Your customers’ birthday is an event you simply can’t leave unnoticed. Pleasant gifts, warm wishes and festive images are more than welcome.

Customer's birthday in an email campaign

  • 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.

Below, there is a list of events that deserve to be mentioned and celebrated in your email campaigns in September. So what if Eat an Extra Dessert Day or National Milkshake Day are local holidays? A few people would refuse to celebrate whatever that involves eating sweets or drinking milkshakes, don’t you agree? Take a look at other fancy occasions to include in your welcome campaigns, reactivation emails or newsletters, and take your email marketing to a whole new level.
