Squarespace Campaign Monitor Integration
Campaign Monitor is common in organisations that chose it years ago and have no intention of moving. Connecting Squarespace to it is straightforward, provided the custom fields are created in the right order.

What connecting Campaign Monitor to Squarespace involves
- Signup and enquiry forms writing into the correct subscriber list.
- Custom fields created in Campaign Monitor before the first submission, since unrecognised fields are dropped rather than flagged.
- Consent and preference capture where your sector requires it.
- Suppression handling, so unsubscribes are not quietly re-added by a form.
The part that usually goes wrong
Campaign Monitor distinguishes between a subscriber who unsubscribed and one who was never subscribed. A badly built form re-subscribes people who opted out, which in the UK is a compliance problem and not just an annoyance. We check the resubscribe behaviour explicitly.

How it is built
There are four ways into Squarespace: native integrations where one exists, embed and code blocks, code injection, and an automation layer such as Zapier or Make. Choosing the right one is most of the job. We pick the route that needs the least maintenance rather than the one that is quickest to build, because you are the one who lives with it afterwards.
Integrations are written defensively, with feature detection rather than assumptions about Squarespace internals, and fallbacks that fail quietly rather than visibly. Everything is commented and handed over with a note on what it does and where it lives. If it breaks after a Squarespace update, our support service covers fixing it.
What it costs
Integration work is $100 an hour, scoped with a fixed estimate before we start. Most single-tool integrations land between one and six hours. If your setup turns out to need more than that, we tell you before doing the work rather than after. Read more about how we handle Squarespace integrations generally.
Campaign Monitor and Squarespace questions
It can, if built carelessly. Campaign Monitor has settings that govern this and they are not all safe by default. We set them deliberately and test with a previously unsubscribed address.
Yes, provided the field exists in Campaign Monitor first. We create the fields, then map them, then test, in that order.
If it works and your team knows it, yes. Migrating email platforms costs more than people expect and rarely improves results on its own. We will not push you to move.
