160+ Creative Ideas to Fill Your October Content Calendar

Although it feels like September has just begun, and it’s been not too long since all those back-to-school campaigns, a smart email marketer knows it’s time to think ahead to October content ideas. Successful email marketing relies on quality content that engages, entices and inspires subscribers to go to the website and make a purchase. And it can be difficult to create content for people who are saturated with information. According to the survey, 34% of email marketers consider content creation to be one of the most difficult phases of email production. First, you need to choose an interesting topic that your audience will be curious about. Then you can fill your emails with content based on the chosen topic and your business goals. 

We’ve collected more than a hundred interesting ideas for the October marketing campaigns. These include both popular and unusual holidays and events. We have also included email examples highlighting how you can use these occasions in your newsletters. For more inspiration, check out our email collection.

While you have time, think about how you can take advantage of these newsworthy events. For example, during the Walk Your Dog Week, remind your audience to take their four-legged pals outside and give them a good run. Not all of your subscribers may have a pup, so a list of local shelters offering fostering and adoption might be worth sharing as well. Or you may send an October email featuring recent studies and articles on the benefits the dog ownership brings, or prepare a special infographic sheet based on them.

If the above October marketing ideas hardly resonate with your business and audience, here are day-by-day October ideas to help you design a month-long marketing strategy, with the best marketing content examples attached.

Choose events associated with what you’re doing, and come up with an unusual way to present it to your subscribers. Analyze what campaign format worked or didn’t work previously, and bring in some changes. Consider sprucing your newsletter with a GIF, or add a bit of interactive vibes into your event-inspired promo with a rollover effect.

Remember that holidays are all about fun and laughter. So, whatever the marketing campaign, make it positive and festive, and don’t forget to reinforce your verbal congratulations with a little gift: a free shipping code or monthly subscription would definitely set the mood.
