It is more about long-term deliverability than just quick tests. Some special trial period might be available with a coupon code, but don't expect a free tier to just mess around with.

Well, email warmup usually takes a few weeks, like between two to four weeks. It depends on how old your domain is and how much email you plan to send. Newer domains might need a bit more time, and older ones with some history might warm up quicker. The important thing is keeping that volume slowly increasing and consistent engagement up.
