Who's done DNS setup instructions well?

Hi guys.

Setting up three DNS hosts is the key task that our users must complete before moving on to sending their first emails with Coresender.

While talking to our customers we've learned that unfortunately one-instruction-fits-all approach is not enough. That's why we're going to ask our users for their DNS provider and then provide hosts and targets in a format that's compatible. Some will probably also need help finding domain settings within their hosting account.

I'm looking for example fellow SaaS companies who did this step well enough for not-so-technical users. Especially something that doesn't involve a multi-page instruction to be followed. Maybe someone have seen something creative and would like to point me in the right direction?

Thank you in advance!
