Constant Contact to HubSpot migration

Constant ContactHubSpot Marketing Hub

Short answer

Moving from Constant Contact to HubSpot brings contacts, lists, unsubscribes and templates into HubSpot, so email marketing runs on the same platform as the CRM, with automation and reporting tied to pipeline.

Why firms make this move

Constant Contact is simple for newsletters, but firms that want segmentation on CRM data, nurture workflows and attribution usually consolidate on HubSpot. The most important step is importing opt-outs and bounces correctly before the first send.

What moves

  • Contacts and lists
  • Unsubscribes and bounces
  • Templates rebuilt in HubSpot
  • Event and survey data where needed

Frequently asked questions

Will unsubscribes carry over?

Yes. They are imported before any HubSpot send.

Should we import every contact?

Not necessarily. Importing only active, consented contacts keeps marketing contact costs down.
