Formspark or Web3Forms: the cheapest ways to run a low-traffic form
For a low-traffic contact form, both can cost nothing. Web3Forms gives you a free allowance every month. Formspark gives you 250 free in total, then sells prepaid bundles that never expire. Both keep a copy of your submissions.
The difference that decides it
The cost structures point in different directions. Web3Forms resets its free allowance monthly, so a steady trickle of messages stays free indefinitely. Formspark's free 250 is a one-time grant, and after that you buy a bundle, but that bundle does not expire, so a small purchase can last years on a quiet site.
The other difference is where a submission can go. Formspark's paid bundle adds webhooks, Slack, Zapier and a REST API. Web3Forms sends email on its free plan and puts webhooks, Google Sheets and its Submissions API on paid plans.

"Not a documented feature" means it is not in their published documentation as we read it, not that it can never be done. Check with them before ruling something out.
Which to choose

Choose Web3Forms when email is enough, traffic is steady and low, and you never want to pay anything.

A third option, honestly assessed
If you want a free monthly allowance like Web3Forms and more destinations than email, WebForms has both: 300 submissions a month free by email, and paid plans that send each submission to Slack, Discord, Telegram and webhooks at once. It is not the cheapest option once you pass the free tier, and if you never want a subscription, Formspark's model is the better fit.
