Here are a few last-minute and super-effective marketing tactics that you can use for your recurring events:

Use social media to promote your event: Social media is a great platform to promote your event. Create eye-catching graphics, videos, and posts to share on your social media accounts. Use relevant hashtags and tag your event's partners or sponsors to reach a wider audience.

Send email reminders: Send out email reminders to your subscribers to remind them about your upcoming event. Include a call-to-action button in your email, which leads to your event registration page.

Offer Early Bird Discounts: Offer a discount to the first few people who register for your event. This will encourage people to register early and also create a sense of urgency.

Partner with influencers or relevant businesses: Collaborate with influencers or relevant businesses in your industry to promote your event. This will help you reach a wider audience and also build credibility.

Use retargeting ads: Use retargeting ads to target people who have visited your website or shown interest in your event. This will remind them about your event and encourage them to register.

Leverage word-of-mouth marketing: Encourage your attendees to share your event with their friends and family. You can offer incentives for referrals, such as a discount on their next ticket purchase.

Create urgency with countdowns: Use countdowns on your website or social media pages to create a sense of urgency. This will encourage people to register before time runs out.

Remember to tailor your marketing tactics to your target audience, and don't forget to track your results to see what's working best for your recurring events.
