+## Newsletter Checklist:
+
+Related information can be found in [these instructions](https://github.com/InnerSourceCommons/foundation-governance/blob/master/how-to/add-content-to-newsletter.md).
+
+### Gathering Content
+
+**1 month before publication**
+   -  [ ] Gathering content in advance: Add any interesting InnerSource content from slack or social scans or keyword searches for InnerSource / #InnerSource on our social platforms to the next month’s Newsletter Issue in the [GitHub marketing](https://github.com/InnerSourceCommons/InnerSourceMarketing/issues) repo.
+
+
+**2 weeks before publication**
+ - [ ] You may want to ask members for any content they want to contribute. You can do this by sharing a reminder on slack with a link to that month’s Newsletter GitHub issue. 
+(If you do this, be sure to give members a deadline a few days in advance.)
+ - [ ] If you’re posting about a new pattern or a pattern of the month, then be sure to get in touch on the #innersource-patterns channel to say what pattern you plan to post about and see if anyone has any thoughts
+ - [ ] Check in with the team on who should be the Hero of the Month. 
+ - [ ] Check in with Olive about your deadline for working on the newsletter and whether registration links for Community Calls will be ready on time. (We usually issue a brief second update with details of a community call if it’s not confirmed before the deadline.)
+
+### 2 Days before Publication - Drafting the newsletter
+
+- The [Social Media Calendar 2025](https://docs.google.com/spreadsheets/d/12lF2qGSNwxxelIQ2_nq7QLq-Ill6ad2R/edit?usp=sharing&ouid=112227356091295695995&rtpof=true&sd=true) suggests dates for working on and publishing the newsletter.
+- We create and send our newsletter using [Mailchimp](https://mailchimp.com/).
+- Here is a [90 minute video with all the instructions you should need](https://drive.google.com/file/d/1mCZShH5yOj4sKUpKksXGeSkCgiJGHxNw/view?usp=sharing) for creating your monthly newsletter.
+
+**A few pointers**
+
+- All the newsletter images you need should be found here on Canva:
+  - [Community Call Eventbrite Heading Images slides](https://www.canva.com/design/DAE7I9K26k8/q5BJv0-hhtbD5cyRfzTDyA/edit)
+  - [Newsletter Headings](https://www.canva.com/design/DAE6AmIoJGM/8cDqAMRslk72fvBG5OQwUQ/edit)
+  - [Gathering Presentation Slides](https://www.canva.com/design/DAGS5LFv9aU/upxC5BMSGGqp0xmZ_bNXFQ/edit)
+  - The Hero of the Month images are saved [here](https://drive.google.com/drive/folders/1m4rGMjuxz7IgoTDK6-LSKRxDaJ5LB1wB?usp=sharing) in the Social Media & Regular promotion folder.
+  - My go to is unsplash.com when I’m looking for copyright free images.
+  - We use Helvetica, size 15 font for the main body of the text.
+
+- [ ] Go through all the steps in the 90 minute video from above
+
+### 1 Day before Publication - Editing the newsletter
+
+- [ ] Send test emails:
+   - [ ] 1st test email: Check that each link is correct
+   - [ ] 2nd test email: Review that content is correct - especially dates and time for the community calls and events
+   - [ ] 3rd test email: Re-read and do a spell check in your email and by copying and pasting the content in a word document (the word document hack has been really useful for me).
+- [ ] Email link: You need to update the month every time and I always add the year.  
+ 
+### Sending and sharing the Newsletter
+Once you’re happy that the edit has been comprehensive, it’s time to send the newsletter using Mailchimp. (This is covered in the video instructions.
+
+After sending out the newsletter, you then need to share it on social media
+ - [ ] Find an attention-grabbing image to use for the post (I use unsplash.com)
+ - [ ] Draft content to use with sharing the post. The content of the post is always very simple and along the lines of … ‘Hurrah, the [month] newsletter has hit the shelves’ and include a hashtag for #InnerSource
+ - [ ] Share to Linked In
+ - [ ] Share to X and Mastodon
+ - [ ] Share to InnerSource Commons Slack. (Once again, it’s a very similar short message that gets posted on the #general channel that contains the LinkedIn and social links in case people want to repost.)
+ - [ ] Share to other channels as needed, where it may be of particular interest e.g.
+    - the #innersource-patterns channel where I tag the people involved with that pattern
+    - the #marketing working group as a few members repost on social for us
+    - our Hero of the Month
+    - anyone who has advertised an event or activity with us.
