ZenDesk

Zendesk Sell is an inexpensive CRM solution good for small teams needing a simple tool to aid in recording all customer contact (including email and phone conversations). The program is adaptable. Therefore, it is one of small organizations' top customer relationship management systems. Zendesk Sell has four different price tiers. Premium tiers include more tools for monitoring pipelines and coordinating with other programs.

The entry-level plan (billed monthly at $19 per user) should be all you need if you need to keep tabs on emails and a single sales funnel. This plan is feature-light, but it does include group communication and project management resources, making it suitable for small, distributed teams. Email, SMS, and phone call logs may monitor conversations at this level.
