Why do agencies look for Constant Contact alternatives?
Agencies usually look beyond Constant Contact for a free plan, lower prices, or an agency model.
Others want a higher review score.
A fair test is to run one real client list through each option for two weeks. Track setup time, how often the team got stuck, and whether the campaigns were good enough to send without rework. Real use shows differences that feature lists hide.
Cost behaves differently in each tool. Some charge per account with subscriber tiers, some per user, and some have agency plans. Count what you will really use over twelve months, including a separate plan for each client, before you compare headline prices.
Think about the client side. Clients judge your agency by the campaigns and reports they receive, so look at the finished email and the reporting as a client would, and check what a client can see, change, or break.
Finally, plan the move. Export your lists, suppression data and templates, rebuild automations one at a time, and warm up sending gradually so deliverability does not suffer during the switch.
