How we grade them
| 1.8GPAMailshakeWeak | 2.0GPAReply.ioFair | |
|---|---|---|
| Value for money | CStarter's 1,500 sends and one address per person won't carry a sales team, so five people need Email Outreach: $45 a user billed yearly, $45 a head. That's above the category's $40 middle, while most email rivals here charge one price for the whole team. | CNo price is on record: Reply's pricing page answered our reader with a bot check, so there's no per-head figure for a team of five to set against the category's $40 middle. With nothing published, it sits at C. Usage is also metered by active contacts each month. |
| Free plan and trial | FNothing free. There's no free plan and no trial, and Mailshake says it takes payment up front. You can cancel before renewal, but that isn't a trial. | FNothing free is on record. With the pricing pages behind a bot check, we couldn't confirm a free plan or a trial, and an unconfirmed trial can't earn a grade. |
| Features | CEmail sequences with follow-ups, A/B tests, spintax, warm-up and unlimited verification, plus a power dialer on Sales Engagement. The gaps: no LinkedIn steps on record, and rotation and the unified inbox need Email Outreach. | BThe whole job: sequences mixing email, LinkedIn, calls, SMS, WhatsApp and tasks, with A/B variants per step and holiday calendars. Jason AI SDR answers common questions and nudges quiet leads, on autopilot or with approval. Contact search and validation use credits. |
| Ease of use | CNo App Store rating on record. Quick enough to start, since it sends from Gmail, Office 365 or any SMTP mailbox and the AI writer drafts copy, but you still connect accounts and set up your domain. | CNo App Store rating on record. There's real setup: email and LinkedIn accounts to connect, the LinkedIn side through a browser extension, and playbooks and knowledge bases if you want Jason writing for you. |
| Platforms and integrations | BWeb and a browser extension, with Salesforce, Pipedrive, HubSpot and Zapier on Email Outreach and above. No phone or desktop app on record. | BWeb plus a browser extension, with an API, an MCP server and a command-line tool for builders. n8n is the only named integration on record, which is thin next to rivals. No phone or desktop app. |
| Best for | simple per-user cold email, with a dialer | multichannel sequences with an AI SDR |
