Most email platforms charge by the size of your list. That's fair when you're small, but it means your bill grows every time your audience does, even if your income doesn't. Before you commit to any email marketing software, run the numbers.

How to calculate your real email marketing cost

  1. Write down your list size today and where you hope to be in a year.
  2. Look up the monthly price at each size on your platform's pricing page.
  3. Multiply by 36 for a three-year view.
  4. Add any extras: more sending, extra users, or features locked behind higher plans.

Here's a simple example. A platform that costs $50 a month is $600 a year and $1,800 over three years. At $100 a month, it's $3,600. Your own numbers will differ, so run them yourself.

Questions to ask any email platform

  • What happens to my price if my list doubles?
  • Are there limits on how many emails I can send?
  • Are automations and segmentation included, or sold separately?
  • Can I take my list and leave whenever I like?

One-time license vs monthly subscription

A one-time license changes the picture, because the price stays the same however long you use it. Zaap Mail's launch pricing is a single payment: Starter at $11 for up to 5,000 subscribers, or Pro at $17 for up to 20,000. The product page notes that the one-time price applies during the launch period, so check the current offer.

Next steps

Compare your three-year cost with a one-time license, then decide what makes sense for your business.
