How we grade them
| 2.0GPAAiSDRFair | 2.6GPAInstantlyGood | |
|---|---|---|
| Value for money | CNo plan price is published. On your own it's pay as you go, $1.50 per person prospected, charged daily with no monthly fee, so the bill follows how many people Ami contacts. Team plans for 1,000+ people a month are quoted by sales. With no plan price to set against the category, it sits at C. | AA team of five needs Hypergrowth, since Growth's 1,000-contact total and read-only inbox won't stretch that far: $77.60 a month billed yearly for everyone, about $15.52 a head. That's under 60% of the cheaper quarter's $32.50 in this category. |
| Free plan and trial | FNothing free on record: no free plan and no trial. The cheapest way in is a pay-as-you-go campaign from $7.50, which is cheap, but it's paying, not trying. | CNo free plan, but a 14-day trial with no card. It stops at 250 uploaded contacts and 1,000 emails, which is enough to warm up and send a small first campaign, and not much more. |
| Features | BThe whole job: Ami studies your site, finds buyers from LinkedIn and web data, then runs email and LinkedIn sequences with AI call steps through Aircall, bounce checks, warm-up and AI replies. Salesforce sync, LinkedIn signals and voice notes are on Team plans only. | CThe email side is complete: unlimited inboxes and warm-up, multi-step campaigns, A/Z tests, one inbox for replies and automations. But there are no LinkedIn steps at all, and lead search and the AI agents need a separate credits plan from $9 a month. |
| Ease of use | CNo App Store rating on record. Ami does a lot of the thinking, but there's still setup: Gmail or Outlook and LinkedIn to connect, and a look-alike sending domain to add at $33 a month if you'd rather not risk your own. | CNo App Store rating on record. You'll be connecting mailboxes and waiting on warm-up before the first real send, and actually replying from the Unibox needs Hypergrowth. |
| Platforms and integrations | BWeb only, with two-way HubSpot sync, Aircall, Calendly, Gmail and Outlook, and Salesforce on Team plans. No API on record, and no phone or desktop app. | BWeb only, but with HubSpot, Slack, Zapier, Findymail, RB2B and ChatGPT links, webhooks from Hypergrowth and a public API. No phone or desktop app on record. |
| Best for | outbound run by an AI agent, paid per lead | cold email from as many inboxes as you like |
