Pros & Cons
Attio
Pros
- The custom objects and attributes let teams model non-standard processes such as fundraising or partnerships.
- Email and calendar sync builds and enriches contact and company records automatically.
- A Free plan for up to 3 seats and transparent per-seat pricing make it easy to start.
- Pro call intelligence records Zoom, Meet and Teams calls and fills fields from transcripts.
- Developers get API access on every plan, plus webhooks, an App SDK and an MCP server.
Cons
- The native integration catalog is smaller than HubSpot's or Salesforce's.
- Mailbox sending caps make it unsuitable for high-volume outbound SDR teams.
- Plus stops at 10 seats, so the 11th seat forces an upgrade to Pro.
- AI features and workflows draw on credit pools that can run out.
- Reviews say the mobile app has fewer features than the web version, and some report inconsistent support.
Reply.io
Pros
- Covers email, LinkedIn, calls, SMS and WhatsApp in one sequence builder
- Reviewers repeatedly praise fast, helpful customer support
- From 10,000 contacts, Email Volume tiers include unlimited users, which suits growing teams

Cons
- Users say total cost is high once add-ons, credits and telephony fees are added
- The interface feels overwhelming to new users and takes time to learn
- Some users report sync glitches and billing disputes
- It is not a full CRM, so deal and pipeline management needs a separate tool
