The primary differences between a club bulletin and a newsletter are their content and their target readers.  And if one of your club's objectives is to reach potential new members, you're hardly likely to find them inside your own club.

Here's how we define "Bulletin" and "Newsletter".  The former is internal, to keep members informed.  The latter is external, intended to reach non-members, supporters, sponsors, your local community, event attendees, news media and so on.

To distinguish between the two means of communication, use different mastheads / graphics, so as to have greater appeal to the target readership.

Are club bulletins actually read?  When we analyse reader statistics of bulletins, it's usually disappointingly low because members get to know what's happening in their own club simply by attending or through their friends who are also members.

Usually it's absentee members who are motivated to read it.

Club Bulletin Newsletter
Aimed at members. Aimed at non-members (that members receive anyway).
The editor can think like a Club Member The editor must think like a journalist
Published weekly. Published monthly.
Readers limited to members, committed friends and fellow members in other Clubs. Readers unlimited.
Number of recipients usually capped at 25 - 100. Number of readers uncapped - potentially thousands.
Offers little or no value to sponsors and advertisers Potential for strong income generation through wider exposure for sponsors.  Must not become an advertising platform, however.
Readers interested in club matters specifically, Club matters in general. Readers interested in local news, interesting stories, invitations to events - anything except club specific matters.

Distributed by email. Distributed by email.
Rarely leads to membership enquiries. Potentially leads to membership enquiries.
Contains "in jokes", such as sergeants' fines, that are only comprehensible to members. Avoids "Club speak" that non-members may find weird or off-putting.
Contains Club / Organisation acronyms that even many Club members don't understand. Rarely talks about the Club and Organisation at all, other than Club achievements and human interest stories.
Of no value in attracting new members. Valuable tool to reach potential new members.

We often hear the argument "Our members are all too old to even have an email address." or "We've always had a printed bulletin, so we can't possibly change that." 

Here we compare electronic and printed media, whether as a bulletin or newsletter.

Printed Media
Digital media
Expensive to produce, especially if it's full colour. No cost to produce, and always full colour.
Expensive to distribute. Free to distribute.

Difficult to maintain good quality unless money is spent. Easy to maintain quality.
Emphasis is frequently on the physical appearance of the communication. Emphasis is on the content because the layout has no need to be fixed.

Cannot be read on digital devices (phones, tablets, laptops, PCs). Can be read anywhere at any time on any device.
