Honest Comparison

Best SMS Follow-Up App for Real Estate Agents (2026)

TL;DR

For solo real estate agents and small teams who want SMS follow-up to feel personal, FollowUp is the best-fit tool: it sends from the agent's own iPhone via iMessage, uses AI to filter replies, and has a free tier to start. Follow Up Boss is the better fit for real estate teams that need a full CRM with Zillow / Realtor.com integrations and team routing. OpenPhone fits brokerages that need a shared business phone line first. HubSpot fits agents already standardized on a CRM platform. None of the others send from the agent's own iPhone. That is FollowUp's primary differentiation for agents whose buyers and sellers already have their number.

Quick verdict: who should pick which

Choose FollowUp if

Texts come from your own iPhone, so clients see your familiar number
AI reads buyer/seller replies between showings
Free tier to start; no CRM commitment required
You already have a way to capture leads (referrals, open houses, IDX site)

Look elsewhere if

Real estate teams needing full CRM + lead routing → Follow Up Boss
Brokerages that need a shared business phone line → OpenPhone
Agents already on a CRM platform → HubSpot or your existing CRM
Mass-text campaigns to opted-in subscriber lists → SimpleTexting

When to use each

FollowUp

FollowUp is the best fit for the solo agent or small team who already has a way to get leads (referrals, open houses, an IDX site, paid lead subscriptions managed elsewhere) and just wants the follow-up part to be easier. iMessage from the agent's own phone keeps the relationship feeling personal even when the cadence is automated. AI reply classification means the agent only sees replies that need a human response. This matters when you are between showings.

The alternatives

Follow Up Boss is the best fit for real estate teams that need a full CRM with built-in lead routing from Zillow, Realtor.com, and other sources. OpenPhone is the best fit for brokerages whose first need is a shared office phone line for inbound calls and conversational SMS. HubSpot is the best fit for agents who are already on a CRM platform for marketing and want to add SMS as a channel within it.

Pricing

FollowUp has a free tier (3 blasts/day, 10 recipients each) plus per-rep Pro and Business tiers. Follow Up Boss has user-tiered plans with the lower tiers fitting solo agents and the higher tiers built for teams of 10–30+. OpenPhone is per-user with annual discounts. HubSpot has a free CRM tier, but native SMS requires the Marketing Hub Pro tier plus an SMS add-on. For a solo agent doing low-volume follow-up, FollowUp's free tier is the cheapest place to start.

Frequently asked questions

What's the best SMS follow-up app for real estate agents?

For solo agents and small teams that want personal-feeling follow-up, FollowUp is the best fit; it sends from the agent's own iPhone via iMessage, has AI reply classification, and includes a free tier. For larger real estate teams that need a full CRM with Zillow / Realtor.com integrations and lead routing, Follow Up Boss is the better-fit choice.

Is FollowUp the same as Follow Up Boss?

No. They are two separate companies. FollowUp (myfollowup.io) is an SMS follow-up tool for field sales reps including real estate agents. Follow Up Boss (followupboss.com) is a real estate CRM. The name similarity is unfortunate.

Why does sending from a personal iPhone matter in real estate?

Real estate clients are buying or selling the most expensive thing they own. Trust matters. When a buyer or seller sees a text from the same number their agent has been calling them from, the message reads as personal. When they see a text from an unknown business number, it reads as a tool-sent message and gets ignored. iMessage from the agent's own number preserves the personal relationship while still automating the cadence.

What about lead routing for real estate teams?

Follow Up Boss is built for this: round-robin routing, source-based assignment, team handoffs. FollowUp has lighter workflow assignment but does not match Follow Up Boss's routing depth. If lead routing across a 5+ agent team is a hard requirement, Follow Up Boss is the better fit.

Do any of these integrate with Zillow or Realtor.com?

Follow Up Boss does, with direct connections to 200+ real estate lead sources including Zillow and Realtor.com. FollowUp does not currently have direct lead-source integrations; you import contacts manually or via iOS contacts. If lead-source integration is required, Follow Up Boss is the better-fit tool.
