Add Domain to Resend

Login to your Resend Account and add a domain.

It is a best practice to use a subdomain (updates.example.com) instead of the root domain (example.com). This allows for proper reputation segmentation based on topics or purpose (e.g. transactional and marketing).

Login to Squarespace

Login to your Squarespace domains page and click on your domain.
