Seamless.AI vs Unify (2026): which should you pick?

Pick Seamless.AI if

• Fits if you want contact data, emailing and a dialer from one company
• Works for companies ready to agree a contract with a sales team, prospecting on LinkedIn in Chrome

Look elsewhere if

• Not for you if you want to see a price before talking to sales
• Tight if you're on Basic, with 250 credits a month per user, refreshed on the contract date
• Skip it if you want a free plan that keeps going, as the 50 credits are a one-off
• Watch out: buyer intent searches use a separate allowance of intent topics, not your credits

Pick Unify if

• Fits if you are a small team that wants prospecting and sequencing under one login
• Works for people who want to start on a free plan with up to 3 seats

Look elsewhere if

• Tight if you stay free, as credits are limited and extra credits are for paid plans only
• Skip it if you need website intent or an open API, as those are Business features
• Watch out: managed mailboxes are Business only, at $25 per mailbox a month
• Pricey if you scale seats, as Pro is $60 per seat a month
