Pros & Cons
Microsoft Dynamics 365 Sales
Pros
- Works natively with Microsoft 365 and the Dynamics 365 and Power Platform stack, which suits firms that already run on Microsoft.
- Deep customization and automation, which reviewers often name as a key strength.
- Copilot features and prebuilt AI agents are included from the Enterprise tier, and Premium bundles 1,000 Copilot Credits per user each month.
- Flexible licensing, including attach licenses for existing Dynamics 365 users and device licenses for shared machines.
Cons
- Steep learning curve, the most common complaint in G2 reviews (3.8/5 average from about 1,600 reviews).
- Setup and customization are complex for non-technical users and usually need an admin or partner.
- Advanced features and AI capacity cost extra, and Premium more than doubles the per-user price of Professional.
- The Professional tier has limited customization, which pushes many buyers to the $105 Enterprise tier.
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
- Native HubSpot, Salesforce and Pipedrive syncs plus Zapier
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
