LGTM

Left a suggestion to easily direct people to their email client. If thing we should also add a body with the things we want from them already filled in

Suggested change

You have a list of CIDs for content you have stored in IPFS already and would like to import that content into NFT.Storage. To be able to do so, you must be added to an allowlist for using the Pinning Service API. If you would like to be added, email `support (at) nft.storage` with your project name and a description, a public profile link for you or your project (Twitter, artist profile, etc.) and 5-10 CIDs of content you're looking to pin.

We could even add a body with email template with the things we want. For doing that, the URL would look be like:

mailto:support@nft.storage?subject=Pinning%20API%20access&body=Hello

Note that text must be encoded with something like this: https://www.urlencoder.org/

See example https://www.w3docs.com/tools/code-editor/1181

(this would likely be cool to add to every place we direct people to sending an email!)
