  2. Create a Zap with your trigger.Pick any of Zapier's 6,000+ apps as the trigger — Stripe, Typeform, Google Sheets, HubSpot, Salesforce, anything.
  3. Add a Webhooks by Zapier action.Choose “POST” as the action event.
  4. Configure the request. URL: https://app.nexuspromail.com/api/v1/api/send. Add an Authorization header with value Bearer YOUR_KEY. Add a JSON body with to, from, subject, html (or template_id).

Common Zapier + NexusProMail Patterns

Typeform → confirmation email

Typeform submission triggers; map answers into NexusProMail template variables; send personalised confirmation in seconds.

Stripe → receipt + tag

Stripe charge.succeeded webhook → POST a receipt via NexusProMail → also POST the contact to a customer-segment list.

Calendly → reminder

Calendly invitation created → schedule a NexusProMail send 24h before the meeting time → calendar invite includes call link.

Google Forms → multi-recipient

Form response → branch by answer → send different templates to different teams (support, sales, ops) via the same Zap.

HubSpot → segmented send

HubSpot contact property change → POST contact update to NexusProMail → contact moves to the matching segment for next campaign.

NexusProMail bounce → CRM cleanup

Webhook from NexusProMail (bounce) triggers Zapier → updates CRM contact status → flags for sales follow-up to verify the correct email.

An Honest Note on Zapier and Schrems II

Zapier is operated by Zapier Inc., a US-incorporated company. Personal data flowing through Zapier triggers the same third-country-transfer questions as any US-hosted middleware regardless of which downstream services it calls.

For EU teams with strict Schrems II posture, this matters: using Zapier as middleware in front of NexusProMail introduces a US-jurisdiction processor (Zapier) into the chain, partially neutralising the EU-jurisdiction advantage of NexusProMail at the email layer. Whether this is acceptable depends on what data flows through and your DPIA conclusions.

The cleaner alternative for Schrems-II-strict teams is self-hosted n8n — same automation power, no US-jurisdiction middleware. See our n8n integration page for the comparison.

Zapier integration FAQ

How does the Zapier integration work?+
Two options. First: use Zapier's built-in Webhooks by Zapier action with a POST request to the NexusProMail REST API — this works today, no NexusProMail app required, and gives you full API surface access. Second: install the NexusProMail Zapier app (in private beta, contact for early access) which exposes pre-configured Send Email, Add to List and Update Contact actions in the Zapier UI. The Webhooks approach is what most teams use in production because it requires no waiting on the app review.
What's a typical use case?+
Three common Zaps: (1) Typeform / Google Forms submission → send confirmation email + add contact to list; (2) Stripe payment received → send receipt + add to customer segment; (3) Calendly meeting booked → send calendar invite + reminder sequence. Zapier handles the trigger source variety; NexusProMail handles the email delivery and EU-jurisdiction processor role.
Does using Zapier break my Schrems II posture?+
Honest answer: Zapier is US-incorporated, so personal data flowing through Zapier triggers the same third-country-transfer questions as any US processor. Whether this matters depends on what data passes through. Names, emails and behavioural signals are personal data; processing them via Zapier is a Schrems II event regardless of which destination receives them. For EU teams strict about Schrems II, n8n self-hosted in the EU is the cleaner alternative — see our /integrations/n8n page.
How do I authenticate the Webhooks call?+
NexusProMail uses Bearer API key authentication. In Zapier's Webhooks action, add a Header named “Authorization” with value “Bearer YOUR_API_KEY”. The API key is issued on signup — use the sandbox key for testing and the production key for live workflows. You can store the key in a Zapier secret to avoid leaking it across Zap clones.
Can Zapier receive webhook events from NexusProMail?+
Yes. Create a Catch Hook trigger in Zapier; Zapier issues a unique URL; register that URL as a webhook endpoint in NexusProMail. Delivery events (delivered, opened, clicked, bounced, complained, unsubscribed) now fire into your Zap. You can route them to a CRM, log them in Airtable, or trigger downstream automations.
What's the cost model when sending via Zapier?+
Three layers: (1) NexusProMail charges per the plan you're on — sends count against your plan ceiling regardless of trigger source; (2) Zapier charges per Zap task — each Webhooks action consumes a task; (3) The trigger source may have its own pricing. For high-volume sends, the Zapier task cost dominates fast — most teams batch through their own backend at scale and reserve Zapier for low-volume or unusual triggers.
What if Zapier rate-limits me?+
Zapier has per-Zap and per-account task throughput limits. NexusProMail also has per-account API rate limits. For high-velocity sends, use our batch send endpoint via a single Webhooks action with an array of recipients rather than one Webhooks action per recipient. Cuts Zapier task consumption to 1/N and avoids both rate limits.
Can Zapier handle multi-step email sequences?+
Yes, with Zapier's Delay and Path actions you can build sequences (e.g. send email A → wait 24h → send email B). For sequences longer than 2-3 emails or with complex branching, the orchestration usually belongs in NexusProMail (campaign builder with multi-step automation) or in n8n (open-source alternative). Zapier is best at simple trigger → email patterns.
