Although it feels like September has just begun, and it’s been a while since all those back-to-school campaigns, a smart email marketer knows it’s time to plan October content ideas. Successful email marketing relies on quality content that engages, entices and inspires subscribers to visit 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.

Choose events associated with what you’re doing, and come up with an unusual way to present it to your subscribers. Analyze what campaign formats worked or didn’t work before, and make changes. Consider sprucing up your newsletter with a GIF, or add a bit of interactive vibes to your event-inspired promo with a rollover effect.
Remember that holidays are all about fun and laughter. So, whatever your marketing campaign, keep it positive and festive, and don’t forget to reinforce your verbal congratulations with a little gift: a free shipping code or a monthly subscription would definitely set the mood.
