Comparing shared inbox tools for small teams

If your team shares one business phone number for calls and texts, the tools people usually compare are OpenPhone, Aircall, Dialpad, and (the reason we built this) Ringpost. The marketing pages all look similar (shared inbox, call routing, texting), so here's what actually differs once you dig in.

Pricing model, not just price

The number that matters most isn't the sticker price, it's whether it's per seat. OpenPhone (now Quo) runs $19/month per user, Aircall $30–40/month per user, Dialpad $15–27/month per user, all published rates at time of writing, and all multiply by headcount. A 5-person team on any of those is paying $95–200/month before a single call is made. Ringpost is a flat $10/month per team regardless of size, with Twilio billing usage (calls and texts) directly and separately. For a similarly-sized team with moderate usage, that's often a large majority cheaper, though the exact number depends on your actual call/text volume.

That flat-fee model only works because Ringpost isn't reselling Twilio, it's a CRM layer on top of an account you connect yourself. That's a real trade-off, not a free lunch: worth understanding before you switch.

The feature that actually decides it

Price gets the attention, but talking to teams actually evaluating these tools, the deciding factor is usually something else entirely: can you hand a specific conversation to one person and know it's theirs? A shared inbox where everyone can see every message has an obvious failure mode: everyone assumes someone else already replied, and a customer gets ignored or texted back three times by three different people. The tools that solve this well let you claim a conversation with one click, see an "Unassigned / Mine / All" split, and, critically, actually flag or reassign anything that's sat unanswered too long, not just offer the setting and leave it off by default.

That last part matters more than it sounds: most of these tools ship an unanswered-conversation alert as an optional rule you have to remember to turn on, and most teams never do. Whichever tool you pick, that's the one setting worth checking during a trial, not assuming it's already protecting you.

Who each is actually for

• OpenPhone / Aircall / Dialpad: teams that want everything bundled and don't want to touch a carrier account directly, and are fine with per-seat pricing as the team grows.
• Ringpost: teams comfortable connecting their own Twilio account in exchange for flat, non-per-seat pricing and direct, unmarked-up usage costs.
