Industries — Real Estate & Lead Gen

Property mail with the reply data you were losing.

Property inquiry mail flowing both ways — outbound quality-gated, inbound classified and parsed for the buyer's real coordinates.

Inquiry replies enrich the lead
Real Estate & Lead Gen

Four sendrules capabilities mapped to the pain that defines this segment. Every one of them is on the free plan.

  • Inbound classification
  • Custom regex extractors
  • Quality gate on outbound
  • Webhook to your CRM
The pain

What you deal with today.

Portal-generated buyer inquiries come with a masked address. Their reply doesn't. The reply often carries the buyer's real email, a phone number in the signature, and a note about their timeline — data your CRM would love to have. Today it sits in an unread inbox because your sequencing tool doesn't parse it.

How sendrules answers

What changes when you route through us.

sendrules receives every reply, classifies it, and runs your custom rule-based parser to extract the buyer's real coordinates (email in signature, phone in body, timeline mention) into a structured list row. The webhook fires and your CRM has the enriched lead before the agent sees the reply.

The four capabilities

Feature per pain, not the other way round.

Inbound classification

Every reply is tagged reply / bounce / OOO / unsubscribe / other and lands in the right inbox — with the source thread ID for CRM association.

Custom regex extractors

Write a rule per inquiry template — capture email, phone, budget, timeline into named fields on the list row.

Read more →

Quality gate on outbound

Portal-supplied addresses are frequently typo'd. The quality gate catches them before your ESP sees a bounce.

Read more →

Webhook to your CRM

HMAC-signed webhook per new list row, retried with backoff. Land the enriched lead in Salesforce, HubSpot, or your own CRM within seconds.

Where it lands

Concrete scenarios you can wire in this week.

  • Inquiry replies parsed into 'buyer with phone + timeline' rows before the agent even opens the mail
  • Outbound property alerts with the quality gate rejecting portal-supplied typo'd addresses
  • Per-office tenant with each office running its own DMARC posture and provider fleet
  • OOO replies parsed for the agent covering during holidays, delivered to whoever is on cover
  • Signed webhook fed into the CRM so lead enrichment happens without a human step
