Most comparison tables list hundreds of features. A small shop uses a handful of them. These four decide whether a platform suits you.
1. How well it connects to your shop
The platform needs your order, product and basket data to send anything useful. Without it, an abandoned cart email cannot show what was left in the basket. Shopify connects well to most of them. Squarespace, Wix and marketplaces have fewer good options.
2. What it costs at your list size
Most platforms charge by the number of contacts. A tool that is cheap at 500 contacts can be expensive at 15,000. Check the price at double your current list, not just today's.
3. How deep the automation goes
Every platform can send a welcome email. Fewer can branch a flow based on what someone bought, or hold back a campaign from people who are already in a flow.
4. Whether you will use it
The cheapest platform you log into every fortnight beats the best one you avoid.
