Step 2: Enable the Sendlane Sync
Once Textiful is authorized, you'll need to enable and customize how email addresses are synced to Sendlane.
On the keyword details page in Step 3, check the "Sync collected email addresses to my email list" box. Below that check the "Sync Emails to Sendlane" box.
If you do not see the Sendlane checkbox, click the "Add more email integration options" link to go to the Integrations page and follow the instructions in Step 1 above.
Step 3: Customize the Sendlane Sync
Click the "Sendlane" tab in the left hand navigation to view all of the Sendlane Sync options.
Select a Sendlane List
From the dropdown, select the Sendlane list that you would like all collected email addresses to be added to.
Select Sendlane Tags
You can also check one or more tags to be applied to your email addresses once they are subscribed to Sendlane.
Choose Data to Sync
By default, Textiful will sync just the email address to Sendlane. You can chose to have additional data to sync to the Sendlane list by clicking the "Add Data Field To Sync" link. Select a Textiful data field that you want to sync to the selected Sendlane merge tag.
