How to search for newsletter issues
Reletter's issues search makes it easy to find newsletter issues for the topic or niche that you care about. This guide explains how to use the search engine and gives you some tips and best practices.

Enter a search query (eg. real estate investing or marketing) and hit enter to see the most relevant issues for your search term.

Advanced search filters let you slice-and-dice millions of newsletter issues in all kinds of new ways to find the ones you're looking for.
For example: show me the most recent issues about "real estate" (excluding the keyword "investing") from Substack newsletters with more than 5,000 subscribers.

You use the following search operators to narrow down your results:
Description | Example |
Either terms can match | real OR estate |
Both terms must match | real AND estate |
Exact phrase | "real estate" |
Don't match | -investing |
Grouping | (real estate) OR (property investing) |
