Can I re-enter Thailand on a 60-day visa exemption after staying one night in another country?

It is possible to re-enter Thailand on a 60-day visa exemption after staying out of the country for one night, such as in Malaysia. However, there are no official limits to how many times you can use the visa exemption, and it largely depends on the discretion of the immigration officer at the border. If you do not have a recent history of excessive travel in and out of Thailand, you should generally be okay. It's advisable to ensure you are not perceived as misusing visa rules based on your travel pattern, and consider obtaining a 30-day extension at a local Thai Immigration office for added security.
