I'm pretty far into the degoogling process, and I'm thinking about purchasing a domain and using it for email. I realized I don't want to be stuck with any one email service, so this is pretty much a necessity for me.
I wouldn't self host though, because I understand that's very hard to do.
For people who have already done this: are there any pitfalls or things I should take into consideration before I purchase a domain?
Also, does the tld matter? Are my emails more likely to be sent to spam with a custom domain vs an email provider's?

Make sure your chosen email provider supports DMARC. Since I'm sure someone is wondering, yes, Proton mail does.

Absolutely, but only if you choose not to setup DMARC and DKIM
Every mail provider, that I have encountered, that supports custom domain names, provides a detailed step by step guide for which DNS records to add. Follow the guide, don't skip any steps, and make sure to finish.
I see some providers support DANE. Is that different than either DMARC or DKIM? I looked it up, but the description was very technical and didn't clear up the differences for me.
