What you get

Three ways Mailsfinder plugs into HubSpot

Real-time enrichment on contact create, bulk back-fill for legacy lists, and custom property mapping that fits your existing schema.

bolt

Webhook-driven enrichment

HubSpot fires a webhook the instant a contact is created. n8n picks it up, calls Mailsfinder Finder + Verifier, and pushes the verified email back into a custom property in under 4 seconds. Forms, list imports, and Sales Navigator scrapes all flow through the same pipe.

cleaning_services

Bulk list cleaning

Re-verify your entire HubSpot contact database in one batch run. Flag bounce-prone, role-based, and catch-all addresses before your next big send. 50,000 contacts cleaned in roughly 14 hours of background processing at no extra cost on the Monthly plan.

tune

Custom property mapping

Write Mailsfinder output to any custom HubSpot property you want. mf_verified_email, mf_email_status, mf_enriched_at, company domain, role, confidence score. Your RevOps schema stays clean and your SDRs see exactly what they need on the contact record.

How it works

Four steps from raw contact to verified record

Set up takes about 20 minutes. After that it runs in the background for every contact your HubSpot CRM creates.

Install the workflow template

Import the Mailsfinder template into n8n, Make, or Zapier. One JSON file, pre-wired with the webhook trigger, Finder call, Verifier call, and HubSpot update step.

Connect HubSpot and Mailsfinder

OAuth into your HubSpot portal, paste your Mailsfinder API key, and create the custom contact properties for verified email, status, and enriched timestamp.

Trigger on contact create

Subscribe to the contact.creation webhook in HubSpot. Every new contact, whether from a form, CSV import, or chatbot, fires the workflow and starts the enrichment chain.

Verified email lands in HubSpot

Mailsfinder finds the email by name + domain, verifies it, and writes the result to your custom property. SDRs see a clean record. MQL routing rules can branch on confidence score.

Deep dive

A workflow that fits any HubSpot schema, on every tier

No Operations Hub Professional required. The n8n template below subscribes to HubSpot's free contact-create webhook, calls Mailsfinder, and patches a custom property. Make and Zapier versions are functionally identical.

HubSpot use cases

Four motions RevOps teams run on day one

From inbound form fills to ABM committee discovery, the same Mailsfinder workflow covers every enrichment scenario.

description

Form-submission enrichment

Visitor submits a HubSpot form with first name, last name, and company but a personal Gmail. Mailsfinder finds and verifies their work email, writes it to mf_verified_email, and SDR routing fires on the cleaned record.

groups

ABM committee discovery

Target account lands one MQL. Use Mailsfinder Domain Search to pull every public email at that company, push the buying committee into HubSpot as associated contacts, and run a coordinated multi-thread outbound play.

upload_file

List import cleanup

A trade-show CSV with 4,000 contacts hits HubSpot. The workflow verifies every email, flags bounces, finds missing addresses by name + domain, and quarantines junk before your next nurture campaign torches sender reputation.

verified_user

MQL handoff to sales

When a lead crosses an MQL score threshold, fire the workflow to verify their email, append role and seniority, and only then create a HubSpot Deal. Sales gets clean records, marketing keeps its handoff SLA.

FAQ

Questions HubSpot admins ask before wiring this up

Is there a native HubSpot app for Mailsfinder, or do I need n8n, Make, or Zapier? expand_more

Mailsfinder connects to HubSpot through n8n, Make, and Zapier using the contact-create webhook and the Mailsfinder API. A native HubSpot marketplace app is on the roadmap, but most RevOps teams prefer the workflow approach because it lets you control retry logic, custom property mapping, and conditional enrichment without paying for HubSpot Operations Hub Professional.

Do I need HubSpot Operations Hub to run Mailsfinder enrichment workflows? expand_more

No. The Mailsfinder workflow uses HubSpot's free webhook subscription via the developer API, which is available on every HubSpot tier including the free CRM. Operations Hub Professional is only required if you want to run the entire automation inside HubSpot Workflows using custom code actions. n8n, Make, and Zapier sidestep that requirement entirely.

How does Mailsfinder compare to HubSpot Breeze enrichment for cost? expand_more

HubSpot Breeze Intelligence enrichment runs roughly $30 per 100 credits at the lowest paid tier, which works out to about $0.30 per enriched contact. Mailsfinder Monthly at $9.99 gives 300,000 credits per cycle, which is about $0.00003 per credit. For teams enriching more than a few hundred contacts per month, Mailsfinder is dramatically cheaper while delivering the same data points: verified email, role, company.

Is the workflow GDPR compliant for EU contacts in HubSpot? expand_more

Mailsfinder is GDPR-compliant and processes data under a Data Processing Agreement available to all paid customers. For EU contacts specifically, you can add a region check in the n8n or Make workflow to skip enrichment for contacts in countries where you do not have a lawful basis. Most teams enrich only B2B work emails, which fall under legitimate interest for B2B outbound under GDPR Article 6(1)(f).

What are the rate limits when bulk re-enriching an existing HubSpot contact database? expand_more

Mailsfinder Monthly and Annual plans run at 600 requests per minute on Finder, Verifier, and Enrichment APIs. HubSpot's own API caps at 100 requests per 10 seconds on Pro accounts, which is the actual bottleneck on bulk back-fills. A 50,000-contact re-enrichment typically finishes in 12 to 18 hours of background processing, depending on your HubSpot tier.

How do I map Mailsfinder data to custom HubSpot properties? expand_more

Create custom contact properties in HubSpot for the fields you want from Mailsfinder, such as mf_verified_email, mf_email_status, mf_company_domain, and mf_enriched_at. In your n8n or Make workflow, add a HubSpot Update Contact step after the Mailsfinder Find Email step and map the API response fields to those custom properties. The Mailsfinder docs include a copy-paste property schema for HubSpot.

Will the workflow overwrite existing emails on HubSpot contacts? expand_more

Only if you tell it to. The recommended pattern is to write Mailsfinder results to a separate custom property like mf_verified_email and leave the primary email field untouched. Your team or a downstream HubSpot workflow can then promote the verified email to the primary slot after review. For high-confidence overwrites, add an IF branch in n8n that only overwrites when the verifier returns a 'valid' status with confidence above 95%.

Does the workflow handle role-based addresses like info@ or support@? expand_more

Yes. The Mailsfinder Verifier flags role-based addresses, catch-all domains, and disposable emails in its response. You can branch on this flag in n8n or Make to either skip the contact, route it to a manual-review queue in HubSpot, or attempt a name-based re-find using the contact's first name, last name, and company domain.
