The verdict
If you have no email tool, or your emails look rough and you cannot tell what performs, I'd pick Campaign Monitor first.
If you already send decent email and a demo request, application or onboarding form is where people vanish, I'd pick Typeform and use it only where conversion pays back.
Typeform is slower for long, simple lists of fields, so do not move every form over. Test completion on your own audience first. Typeform lists integrations with HubSpot, Salesforce, ActiveCampaign, Klaviyo and Zapier, so check how answers would reach Campaign Monitor.
