What is in the HubSpot form field plan?
A spreadsheet with five tabs: how to use it, a form inventory with each form's purpose, pages, editor, consent option, follow-up and owner, a field plan mapping every field to its property and object, a launch checklist of settings that break forms quietly, and a monthly review that calculates conversion rate. It opens in Excel, Google Sheets or Numbers.

How do you plan a form with the template?
Add the form to the inventory first: its purpose, the pages it appears on, the consent option and what happens after submit. Then list every field in the field plan with its label, property internal name, object and type, whether it's required or hidden, any pre-fill or query string parameter, and one line on why you ask for it.

Which settings does the launch checklist cover?
The ones that fail without an error: embedding domains missing from the allowed list, which sends submissions to spam; CAPTCHA blocking an integration's API submissions; consent text and checkboxes; email domain blocking; the setting that decides whether unknown emails create new contacts; notification recipients; follow-up emails reaching only marketing contacts; and a test submission checked against the field plan.
How do you use the monthly review?
Each month, copy views, submissions and spam submissions for each form from HubSpot; the sheet calculates conversion rate as submissions divided by views, matching HubSpot's definition. Note any change you made, such as removing a field, so you can see what helped. Leave forms fed by the API out, since their submissions don't record views.

Form planning checklist
Key takeaway: Decide what each form is for and why each field exists before you build, run the launch checklist before it goes live, and track conversion monthly so every change has a reason.
Frequently asked questions
How many fields should a HubSpot form have?
As few as your follow-up needs. Each field should feed routing, scoring, personalization or reporting; if nobody uses it, remove it. Hidden fields can carry details such as lead source without asking the visitor, though HubSpot doesn't allow a required field to be hidden.
What should you check before a HubSpot form goes live?
That every embedding domain is in the form's allowed domains, the tracking code is on the page, CAPTCHA won't block an integration that submits through the API, the consent option and text are right, notifications reach the right people, and a test submission updates the right record and properties.
How do you measure a HubSpot form's conversion rate?
HubSpot calculates it as submissions divided by views, shown in each form's performance view. Enter views and submissions in the template's monthly review tab to track the rate over time and note what you changed. Submissions through the forms API don't create views, so leave API-fed forms out of the comparison.
