Hello @JudyK024 ,
You can add and modify social icons from within the email editor. However, Nextdoor is not an available social media platform to link. You're welcome to submit feedback for voting and consideration on the feedback boards. In the meantime, you can link to your Nextdoor page by adding a regular button, text, or image link into your email.
Thanks for confirming. Aligning the added Nextdoor image with the social icons is the challenge. I will submit the feedback for consideration. It's a pretty key social platform for small business and nonprofits. Thx.
