How we grade them
| 2.6GPAContactOutGood | 2.4GPASeamless.AIFair | |
|---|---|---|
| Value for money | COne person pays $39 a month billed yearly for emails, or $79 with phone numbers, right at this category's middle ($39). Self-serve is one user per company, so a team of five gets a quote from sales, with no figure on record. | CNo prices are published, as the pricing page is a sales form, so it sits at the ordinary grade with no five-person figure. Its help center lists 250 credits a month per user on Basic and 10,000 on Pro, at 1 credit a contact. |
| Free plan and trial | CA free plan for one user with 5 emails, 5 phone numbers and 5 exports a day, plus the extension and the search portal. Handy for the odd lookup, but 5 a day goes quickly. | CA free license with 50 credits that don't renew. Fine for trying a few lookups, and that's all it's meant for. |
| Features | BWork and personal emails, phone numbers, a search portal with 20-plus filters, a LinkedIn extension, email campaigns, enrichment and recruiting integrations. It covers the whole job, though numbers need the dearer plan. | BEmails, direct dials and cell numbers, a Chrome extension, CRM enrichment, job-change alerts, buyer intent, AI-written outreach, emailing, a dialer and an API. It covers the whole job. |
| Ease of use | BNo App Store rating on record, but it's a Chrome extension on the LinkedIn and Sales Navigator you already use. Open a profile and the details are there. | CNo App Store rating on record. There's a lot in one app, from Autopilot to AI campaigns, and intent topics run on their own allowance, so expect some learning. |
| Platforms and integrations | BWeb and a Chrome extension, with Salesforce, HubSpot, Lever, Greenhouse, Bullhorn, Zapier and Gmail. The API comes with team plans. No desktop or phone apps. | BWeb and a Chrome extension, with Salesforce, HubSpot, Microsoft Dynamics, Pipedrive, Outreach, Salesloft, Zoho and Zapier, plus an API and apps for Claude and ChatGPT. |
