What Software Do You Use for Bulletins and Newsletters?

I use everything in the Google Drive space for emailing, storing the information, schedules, working on the Order of Worship with the Pastors and more for our church, but to make the actual bulletin I use Canva. I created my own template that fits our churches needs and I copy it over and fill in the info to make a new one every week. Keeping it easy. https://www.canva.com/

We use "Word" for our church newsletter and bulletin. Because it's a word processor and not designed for layout, it has all sorts of quirks. Pictures in particular tend to do strange things in Word. It works though. I thought about getting us to switch to Scribus, but, as you say, it is quite difficult to learn. 

I think, depending on your context, word is probably good enough.

We use Canva. We keep it pretty simple. You could check to see if there still is the free Canva plan?

We use Canva (the free nonprofit version) to design materials for the prayer line, weekly updates, and other communications.

Once the designs are complete, we distribute them through Mailchimp (about $15/month), which integrates with Canva for email delivery.

We also continue to use Planning Center. As far as we know, Mailchimp is the only email integration it supports. One limitation of Mailchimp, however, is that it does not allow all attachments. For emails requiring attachments, we therefore rely on Planning Center.

I've been using Publisher as well and am quite sad that it is retiring. For the last month or so, I've been playing around with Word and Canva. I'm leaning on Word since while that's a little more finicky I've been able to figure out the majority of what I need it to do, but I still haven't discovered how to format a Word doc into a 'side fold, half sheet' layout for export into PDF.
