n8n automates marketing by connecting CRMs, email platforms, and web
forms through event‑driven workflows. A single workflow can capture a
form submission, create or update a contact in HubSpot, send a
personalised email via Mailchimp, and route the lead to a Salesforce
queue—all within seconds of the initial click. This guide demonstrates
real implementations using webhooks, field mapping, and conditional
routing for lean marketing teams.

How do you sync web form submissions directly into a CRM like HubSpot?

Connect your form’s webhook to a Webhook trigger in n8n, then add the
HubSpot node to create or update a contact. The Webhook node receives
the raw form data as JSON; a Set node maps field names from your form
to HubSpot’s API field keys. The contact is created instantly after
submission.
[1]

For multi‑property enrichment, the Set node also merges static data
like lead source or campaign name. To sync with Salesforce instead,
swap the HubSpot node for the Salesforce node—both support
upsert by email. For more on data mapping, see our
nodes & expressions guide.

How do you send automated emails via Mailchimp from an n8n workflow?

Use the Mailchimp node with an API key credential to add a subscriber
to an audience, update merge fields, or trigger a campaign. Place it
after the CRM sync node to enrol a new lead into a nurture sequence
automatically. The node’s “Add Member” operation requires the
audience ID and at minimum the subscriber’s email address.
[2]

For personalised content, map contact properties from HubSpot into
Mailchimp merge fields via a Set node. This lets you dynamically
populate the first name, company, or custom fields in the email
template. This entire flow aligns with the
marketing ROI strategies
that turn form fills into revenue faster.

How do you route leads to the correct Salesforce queue using n8n?

After creating or updating a lead in Salesforce, use an IF or Switch
node to read the lead’s country, source, or custom field value. Route
the lead to the correct Salesforce queue by setting the
OwnerId field to the corresponding queue ID. An
Update Record node applies the assignment immediately.
[3]

Queue IDs are static values you can store in an n8n Global Variable
or a Google Sheet for easy maintenance. For multi‑condition routing
(e.g., US leads to queue A, EU leads to queue B), use a Switch node
instead of chained IF nodes. This pattern is described further in
n8n IF & Switch branching guide.

How do you enrich a contact record with additional data from an external API?

Add an HTTP Request node after the CRM node but before the email node.
Call a data‑enrichment API like Clearbit or Apollo, passing the
contact’s email or domain. A Set node extracts the returned company
size, role, or LinkedIn URL and appends it to the contact record in
HubSpot or Salesforce before routing.
[4]

Enrichment data makes lead scoring and segmentation more accurate.
For privacy compliance, always verify the enrichment APIs terms of
use. To handle rate limits on the enrichment API, consider
looping with SplitInBatches
if you need to enrich thousands of contacts in bulk.

How do you build a two‑way CRM sync between HubSpot and Salesforce?

Create two workflows, each starting with the respective app’s trigger
(HubSpot → New Contact, Salesforce → New Contact). When HubSpot
fires, create the contact in Salesforce via its node. When Salesforce
fires, create the contact in HubSpot. A shared lookup key—usually
email—prevents duplicates.
[5]

To handle updates, add an IF node that checks whether the contact
already exists by searching the target CRM. If found, use an Update
operation; if not, use Create. This bidirectional pattern keeps
marketing and sales teams aligned. For production hardening, see our
error workflow & retry guide.

How do you capture form submissions without a native n8n form trigger?

Any HTML form can POST to an n8n Webhook trigger. Configure the
form’s action attribute to the webhook’s Production URL.
The Webhook node in n8n receives application/x-www-form-urlencoded
or JSON data. Set the “Response Mode” to “Using ‘Respond to Webhook’
Node” to send a custom thank‑you page.
[6]

For no‑code forms, integrate Typeform, Google Forms, or JotForm
which offer their own n8n trigger nodes. Each sends a structured
JSON payload you can map directly into a CRM. Regardless of the
source, always validate incoming data with a Set node before writing
to your CRM to prevent dirty data.
