Best Month-to-Month Cold Email Agency 2026: Sales.co With No Contract and a $1,000 Exit

Pricing changed on 2026-09-28. Plans now start at $2,000/month.

A monthly price means little if the contract runs for a year. For this episode we pulled the minimum term, cancellation wording and setup fee from ten cold email agency sites and worked out what a one-month trial would cost at each. Sales.co has the cheapest exit because it combines rolling monthly billing with a zero setup fee and a published price.

• $1,000: one month at Sales.co, then stop, with nothing else owed
• $7,499: one month at CIENCE, which is also month to month but charges a $5,000 setup sprint
• $11,950: the shortest SalesRoads engagement, four weeks with one rep
• Three months: the pilot Martal Group requires before its subscription, price missing
• Cleverly and SalesHive: flexible terms, no dollar figure

Terms and costs for all ten: month-to-month cold email agencies compared
