Instant Lead Follow-Up for Real Estate via iMessage

The Problem

MIT research shows that leads contacted within 5 minutes are 100x more likely to convert than leads contacted 30 minutes later. In real estate, a buyer submitting an inquiry on Zillow or Realtor.com is often submitting to multiple agents simultaneously. The first one to respond gets the conversation.

Most agents respond to new leads in 30 minutes or more — by then, the lead has heard back from a competitor, moved on, or simply gone cold. Every minute you wait is a percentage point off your conversion rate.

Email follow-ups get lost in spam folders or ignored in inboxes already buried under hundreds of messages. Phone calls go to voicemail. iMessage gets read within minutes — it's the channel your leads actually use.

The senderZ Solution

Connect senderZ to your lead sources via webhook. When a new inquiry comes in from Zillow, Realtor.com, your website, or any CRM — senderZ sends an iMessage to that lead within seconds, automatically. You're first in every conversation before you've even looked at your phone.

Two-way messaging means leads reply directly and you see it in your dashboard. Manage conversations, group contacts by property or stage, and send listing updates or open house invites to your entire lead list in one send.

// Your webhook receives a new lead from Zillow
app.post('/webhooks/leads', async (req) => {
  const lead = req.body

  await fetch('https://api.senderz.com/v1/messages', {
    method: 'POST',
    headers: {
      'Authorization': 'Bearer YOUR_API_KEY',
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      to: lead.phone,
      channel: 'auto',
      template: 'lead_followup',
      data: {
        name: lead.first_name,
        property: lead.property_address,
      },
    }),
  })
})
