Textiful allows you to capture email addresses via text message. And good news: they integrate with ConvertKit!
Here's how to set it up:
Create a Keyword.
Once you've created your Textiful account, you'll be prompted to set up a Keyword. You must do this first, because you'll be connecting your Keyword with ConvertKit.
Click "Edit Keyword Settings" to get to your Keyword Settings.
On the left hand side is a menu. Click "ConvertKit Integration."
Connect your Keyword to ConvertKit.
On the next page, you'll be prompted to enter your API Key for your account. You can grab this on your Accounts page.
Use the drop down list to select the Form your want your Subscribers to be sent to.
Test the Connection

Send your email to confirm.
