How we picked
SMS gets opened 95%+ of the time within five minutes — it's the highest-attention marketing channel that still exists. The CRMs below all support SMS as a first-class channel (not a clunky integration), include opt-in compliance tools, and let you trigger sends from CRM events. We weighted native SMS (bundled into the plan) higher than BYO-provider setups, because operational friction kills SMS adoption.
What to consider
- Compliance first — opt-in checkboxes, STOP/HELP keyword auto-handling, opt-out lists synced across the CRM. Skip any tool that makes this manual.
- Native vs BYO Twilio — bundled SMS sending is simpler to ship; BYO Twilio is cheaper at >50K messages/month. Pick based on your volume curve.
- Two-way conversation — if reps need to reply to incoming texts, you need a unified inbox view (Kommo, Salesmate, Tidio are strongest here).
- Segment trigger depth — "send SMS when deal stage = won" is table stakes. "Send SMS when deal stage = qualified AND owner = SDR AND no email reply in 48h" is the dividing line between basic and good.
Pricing snapshot
CRM SMS spend has two parts: license tier (often Pro or Marketing Hub) and per-message cost. HubSpot Marketing Hub Professional is $890/mo and includes a pool of SMS credits. Salesmate Business is $63/user/mo with SMS via Twilio integration. Kommo's Advanced plan at $35/user/mo includes WhatsApp + SMS natively in the messenger inbox.
Trial advice
Send a real-world campaign — 500 contacts, opt-in confirmed, one broadcast and one automated journey — during your trial. Measure setup time, deliverability, and reply handling. The CRM that takes <30 minutes from contact import to first send wins; anything more is a sign your team won't use it consistently.
