Fully customizable

Put your brand experience first. Build your forms your way and we’ll quietly do our thing in the background.

Custom forms

HTML or Javascript, POST or AJAX — we inheret your CSS and collect data from all form elements.

Custom redirects

Send people to custom, branded thank you and error pages instead of our defaults.

Custom email templates

Add your brand logo and colors to our notification and auto-response templates or bring your own.

Custom domains

Make all Basin emails consistent with your brand by sending them through your own domain.

Say goodbye to spam

With automatic filtering and multiple layers of protection, you can enjoy a squeaky clean inbox again.
