I’m looking for a way to check SPF, DKIM, and DMARC is in place for a few hundred domains at once. [dmarcguide.globalcyberalliance.org](http://dmarcguide.globalcyberalliance.org) has a bulk scan option, but their sites keeps breaking even to do one at a time. Anyone know of any other sites/tools with a bulk scan option?

You will probably need to either write something yourself or leverage the API of a paid service.

My favarite tool for checking SPF and DMARC is [checkdmarc](https://github.com/domainaware/checkdmarc).
It’s a CLI tool written in Python. I use it a lot from my Windows 11 WSL.
This tool is really amazing! It can check not only SPF, DMARC records, but also checks it7s validity and warnings if any.
I think you can easily check 100 domains by writing a super simple python or even shell script, dump the results in CSV or JSON files.
For DKIM, I’ve tried several tools, but I haven’t found really good one. I use my own python script to run dig command with selectors supplied from text file.

Hi, i just used this [https://dmarc.cc/](https://dmarc.cc/)
Created a notepad with all 379 domains, and it analized them all for SPF And DMARC, copy - pasted the table reuslt in an Excel without issues afterwards…very nice 🙂
