I have dabbled with this type of offline marketing over some years and have found newsletter style publications to be more effective than flyers. By this I mean, a newsletter that is two or three pieces of paper folded in half, so 8 - 12 pages of content, with highly targeted articles and imagery will yield positive results, or will make you money, perhaps 99.9% of the time. (I wanted to say 100%, but we need to leave room for anomalies.)
So, if you have a tobacco shop, then the newsletter can practically write itself. If you have a grocery store, understand your target audience, then create as focused a newsletter as you can for that audience. Make two of them if you have two different target audiences, and make sure they are easily identifiable as different publications. If you do online business, then what type of business do you do online ... narrow down the scope and hone articles for that audience.
For someone beginning this, I highly recommend you keep this date irrelevant, or not date dependent, meaning do not put articles in it that will expire. Do put a date on the front of it, but keep it broad, like: 2020 Volume 1, or 2020 1st QTR, or 2020 Jan - Mar. This will allow you to get the most out of a single publication.
There are some powerful free software solutions for this type of stuff, and you can print this at home or pay a local print shop to do the work for you (possibly give them a shout out for a discount???)
The key concept to circle around with this type of print marketing is to know your audience, keep it as close to edgy as you can without being offensive, unless that's your niche, and be sure to provide great content. (Hint, you can even reuse content from online if you want, then mention that the reader can find more content like that on your website.)
Also, if you are trying to promote an online business, use QR codes, hashtags, coupon codes, giveaways, and so forth throughout your publication so you can track the readers. Encourage them to provide you with their contact information so you can further market/monetize your new customer/client base.
Please understand that as far as technology has come, print still holds a lot of power. Humans enjoy tangible products. People want high quality goods. If you are offering a solid product or service, and you can put a quality newsletter in their hands, they will respond positively.
One catch that I can think of, is if your organization is some type of activist organization, such as a group that is anti-logging or anti-animal testing or anti-fill-in-the-blank, be sure that your publication reflects your beliefs rather than counters them. Use recycled paper, make sure your ink is properly sourced, and don't use high-carbon emitting distribution channels to tell the world the air is not clean.
