Do I have to pick one integration, or can I use them all?

Use all of them. Salesforce sync + email sequences + webhooks to Slack is a common setup. Each fires independently from the shared event bus — no conflicts.

What happens if Salesforce's API is down?

The outbox queue retries with exponential backoff. When Salesforce recovers, queued events deliver in order. You don't lose anything; you just see a brief sync delay in the admin.

Can I use Pipedrive or another CRM?

Pipedrive native is on the roadmap. Today, use a webhook → Pipedrive via Zapier or Make — a 10-minute setup. Most other CRMs work the same way.

How do I verify webhook signatures?

Every delivery includes `X-Wengrow-Signature: sha256={hex}`. Compute HMAC-SHA256 of the raw body using your webhook secret; compare to the header. Full verification example in the docs.

Can I send transactional email through Wengrow?

For lead-related transactional (thank-you, follow-up) yes. For arbitrary transactional email (e.g. order confirmations), use your own ESP — that's outside Wengrow's scope.

What's the email deliverability rate?

We run on Resend. Branded domains with proper SPF/DKIM/DMARC typically hit 95%+ inbox placement. Shared-domain sending (no custom setup) is lower — set up your own sending domain as soon as you're on Growth+.

Integrations & automations

Salesforce. HubSpot. Email sequences. Signed webhooks. All tier-gated, none bolt-on.

Sync qualified leads to your CRM the moment the conversation ends. Drop them into an email sequence with deliverability already tuned. Or push them to any endpoint via signed HMAC webhook. Pick one, pick all — every integration is built in, not bolted on.

Salesforce — native, with a twist

Available on Growth and above. OAuth connection in about 3 minutes. Every qualified conversation creates a Lead or Contact in your Salesforce org with the fields you mapped.

The twist: every synced record includes an HMAC-signed deep link back to the Wengrow conversation. Your reps can open the full transcript directly from Salesforce — no separate login, no copy-paste. The signed link expires and regenerates; no long-lived tokens floating around.

Features:

OAuth with Salesforce (Classic or Lightning)
Field mapping UI (map Wengrow lead fields ↔ Salesforce fields)
Lead vs Contact routing rules
Rate-limiting built in (Salesforce API limits won't throttle your org)
429 retry with exponential backoff
Per-tenant outbox queue (BullMQ + PostgreSQL) — deliveries retry on failure without duplicating
Audit log of every sync

HubSpot — contact sync + optional deal creation

Available on Growth and above. OAuth setup. Creates Contacts (and optionally Deals) with field mapping. Same rate-limiting + retry + audit log pattern as Salesforce.

Good for HubSpot-native shops that don't want to leave their existing pipeline workflow. Wengrow becomes the AI lead-capture layer in front of HubSpot.

Email sequences — built in

Available on Growth and above. After a qualified lead is captured:

Thank-you email — immediate, branded from your domain.
Follow-up drip sequence — 3-5 messages over 2 weeks, fully editable. Pre-built templates tuned for the most common service-business flows.
Deliverability — guided SPF / DKIM / DMARC setup. Branded from-name. Custom reply-to.
Bounce + unsubscribe handling — automated. We process bounces via Resend, mark hard-bounces as undeliverable, remove unsubscribes from all future sends.
Unsubscribe links — signed with HMAC so they can't be forged; one-click unsubscribe required by Google + Yahoo as of 2024.

You don't need Mailchimp, ActiveCampaign, or a separate ESP for basic lead nurture. If you do need fancier sequences, push to your existing ESP via webhook (see below).

Webhooks — signed, to anywhere

Available on Pro and above. Configure any HTTPS endpoint, pick which events you want:

lead.created — a new qualified lead with all fields
conversation.completed — final transcript when a session closes
lead.status_changed — you or a teammate updated a lead in the admin

Every webhook delivery:

Sent from a rotating IP pool (no DNS hijacking-by-IP)
HMAC-SHA256 signed with X-Wengrow-Signature: sha256=... header
Retries up to 10 times with exponential backoff on 5xx or timeouts
Replay-safe with unique event IDs (don't process twice)
SSRF-guarded destination (no localhost, no private IPs, no AWS metadata endpoints)

Works with Zapier, Make (Integromat), n8n, retool, or any custom endpoint. Push leads into Slack, your data warehouse, Notion, Airtable, a custom Postgres table — anywhere.

Lead alerts — real-time email

Available on every tier. Configure which team members get an email the moment a qualified lead comes in. Includes lead fields, a link to open the conversation in the admin, and a "mark contacted" button.

Throttled so a burst of leads doesn't spam your inbox (configurable digest mode for high-volume operators).
