There are a few ways to grow your audience with GetResponse:

1. Create an opt-in form: Use GetResponse’s opt-in form builder to create forms that you can add to your website, social media channels, or other online platforms. This will allow visitors to sign up for your email list and become part of your audience.
2. Promote your opt-in form: Share your opt-in form on your website, social media channels, and other online platforms to increase visibility and grow your audience. You can also run ads or use other promotion methods to drive traffic to your opt-in form.
3. Offer a lead magnet: A lead magnet is an incentive offered in exchange for a visitor’s email address. It could be a free e-book, a discount code, access to a webinar, or other valuable content. This will help you to grow your audience as people are more likely to sign up for your email list if they know they will receive something of value in return.
4. Create a referral program: Encourage your existing audience to refer their friends and family to your email list by offering them an incentive for each new sign-up. This can be a discount code, a free product, or any other reward.
5. Host webinars: Host webinars on topics related to your business and promote them to your audience. You can use GetResponse’s built-in webinar platform or integrate with third-party platforms. This will help you to attract new audience members and grow your email list.
6. Leverage social media: Use social media channels to drive traffic to your website, promote your opt-in form, and share valuable content. You can also use social media to connect with potential audience members and build relationships.
7. Use email marketing: Regularly sending valuable content to your email list will keep your audience engaged and interested in your business. This will help you to build a loyal following and increase the chances of your audience members sharing your content with others.
8. Create a customer loyalty program: Reward your customers for their loyalty and encourage them to refer their friends and family to your email list.

Remember that building an audience takes time and effort, so be patient and consistent in your efforts. And, always make sure to comply with the laws and regulations on email marketing, such as GDPR, and always get explicit consent to receive emails.
