Bulk sync Flow questions to your ESP
When you have multiple Flow questions that need to sync with your ESP, you can use the bulk sync modal to map them all at once instead of configuring each question individually.
Before you begin: Your ESP must be connected and support custom field creation. This works with Kit, ActiveCampaign, Drip, Klaviyo, and most other ESPs that allow custom fields.
Finding unsynced questions
When you have questions in a Flow that aren't synced to your ESP, you'll see a yellow warning in the Flow editor's sidebar:
"This Flow has warnings: X questions don't sync to [ESP name]. Fix this."
Click the "Fix this." link to open the bulk sync modal.
Mapping questions to custom fields
The modal shows all unsynced questions from your Flow in a table. For each question, you'll see:
The question label and dimension name
An editable field for the ESP custom field name
RightMessage auto-generates field names using a q_ prefix by default. You can change this prefix at the top of the modal, and it'll update all field names automatically.
If a custom field already exists in your ESP with the same name, you'll see a green check icon. RightMessage will map to the existing field instead of creating a new one.
Field name requirements
Custom field names must:
Contain only letters, numbers, and underscores
Be unique (no duplicates in the same sync batch)
Not be empty
The modal shows validation errors immediately if a field name doesn't meet these requirements.
Creating and syncing the fields
Once you've reviewed or edited the field names, click "Create & Map X Custom Fields" at the bottom of the modal.
RightMessage will:
Create any new custom fields in your ESP
Map each question to its corresponding field
Set up the sync so future answers flow to your ESP automatically
You'll see a success message when the sync is complete. If any fields fail to create, you'll get details about what went wrong.
What happens next
After the bulk sync completes, your Flow questions are connected to ESP custom fields. When visitors answer these questions:
Their answers sync to the custom fields in your ESP
If the visitor is already a subscriber, their record updates immediately
If they're new, the data syncs when they subscribe or opt in
You'll need to publish your Flow changes for the sync to go live. Until you publish, the mappings stay in draft mode.
