Turn your newsletter inbox into a searchable knowledge base
Forward any newsletter once and Mailsink saves the source, summary, tags, links, and full email inside your workspace. You get a library you can search later instead of a pile of starred emails.
Save source, summary, tags, and links automatically
Works with Gmail, Outlook, and any forwarded newsletter
Best for researchers, operators, founders, and investors

Why this workflow works
Find the good stuff later
Stop starring emails you never revisit. Save the useful parts into something you can search, filter, and reuse.
Keep links and context together
The result is more than a bookmark list. You keep the source, summary, and original email in one place.
Build a real research habit
Use the same workflow every time a good newsletter lands, so your archive grows without extra effort.
How the workflow feels
1
Create a newsletter inbox
Connect Notion or Airtable, choose the newsletter preset, and get your sink address.
2
Forward the newsletter
Use your normal inbox. Forward one email or set up a rule later if the workflow proves itself.
3
Search and reuse it later
Your workspace now has the summary, links, and original content ready for research, writing, or team notes.
Best fit
This page should immediately make sense for people who treat newsletters as research input.
Founders and operators building their own research library
Investors and analysts tracking recurring industry newsletters
Writers and marketers collecting sources and ideas
Newsletter workflow FAQ
Build the knowledge base once, then let forwarding do the rest
If newsletters already shape how you think and work, they deserve a place better than a cluttered inbox.
