How to Build an Email List for Your Nonprofit (and Why It Matters More Than Your Facebook Page)

Picture this:

A Lions Club in Michigan had 840 Facebook followers built over eight years. In January, their organic reach dropped by more than half — Facebook changed how it prioritizes Page content in the news feed. Their fish fry post, which would have reached 400 people the year before, reached 180. Ticket sales were down 30% that year. They had no email list, no way to reach their supporters directly. Facebook owned their audience. They didn't.

This is not a cautionary tale about Facebook. Facebook is still useful. This is about what happens when you rely on it entirely.

The Difference Between a Facebook Follower and an Email Subscriber

These two things are not equivalent, and most small orgs treat them like they are.

A Facebook follower exists inside Facebook's system. Facebook decides whether they see your content. On any given post, you might reach 10% of your followers — or 5%, depending on recent algorithm changes, how your past posts performed, and what else is competing for attention that day. You cannot contact them directly. If Facebook restricts your account, changes its feed algorithm, or shuts down Pages for your type of organization, you lose access to every one of them.

An email subscriber has given you their contact information directly. You can send them a message at any time, without a platform in the middle deciding whether to deliver it.

The goal is not to abandon Facebook. The goal is to build something Facebook can't take away.

Start With a Clipboard

The simplest email list is a piece of paper and a pen at your events.

Set up a signup sheet at check-in with two columns: Name and Email. Have someone — one specific person, not "whoever" — stand at the door and ask every person who walks in: "Can I get your email so we can keep you updated on our events?"

Most people will say yes if you ask them directly. People who show up to your fish fry or annual dinner are already interested in what you do. You are not cold-calling strangers.

One person at the door consistently asking that question will add 20 to 30 email addresses per event at an 80-person turnout. Over a year of monthly events, that is a real list.

Digital version: Create a QR code that links to a simple signup form. Post it at the event, on your check-in table, and on any printed programs or flyers. Some people prefer to scan rather than write.

Where Else to Collect Emails

Events are the easiest source, but there are others you may be ignoring:

Online donations: Anyone who donates online gives you their email address. Add them to your list, with their permission, per your privacy policy. A donor is your warmest possible contact.
Event registration: If people register in advance, collect email as part of registration. It is expected and nobody thinks twice about it.
Volunteer sign-ups: Anyone who volunteers for your org is interested enough to stay informed. Get their email when they sign up.
Annual dues: You should already have every paying member's email address. If they are not on your list, add them.
Website contact form: Anyone who fills out your contact form is actively reaching out to you. They belong on your list.

When someone donates through Potluck, their email is captured automatically. You can export your donor list and import it into Mailchimp — your donor list becomes your email list.

What to Send and How Often

You do not need a professional newsletter. You need something people will open.

What works:

Event announcements with the date, time, location, and how to get tickets or register. One email, two weeks out. One reminder, three days out.
Fundraising results — "We raised $4,200 at Saturday's fish fry. Thank you to everyone who came out." Short. Specific. People appreciate knowing the outcome.
Volunteer needs — specific asks, specific dates, specific number of people needed. Not "we're always looking for help."
One-sentence updates — "The pantry is open this Saturday. We could use three more volunteers for the 9am shift."

What doesn't work:

Long newsletters with eight articles that took four hours to write and got read by twelve people
Generic "here's what we've been up to" recaps with no specific ask
Anything that sounds like it was written by a committee reviewing the bylaws

Frequency: Once or twice a month is enough for most small orgs. More than weekly and people unsubscribe. Less than monthly and they forget who you are when your email arrives.

The minimum effective email program for a small nonprofit is four to six emails per year: event announcements before each major event, a thank-you after each fundraiser, and one ask in November. That is achievable for any volunteer with 30 minutes per month.

Which Tool to Use

Free options that work for small orgs:

Mailchimp: Free up to 500 contacts and 1,000 sends per month. Simple interface. Widely used, so it is easy to find help when you get stuck.
MailerLite: Free up to 1,000 contacts. Cleaner interface than Mailchimp. Good option if you want something slightly more modern.
Gmail with BCC: Not recommended. It looks unprofessional, has no built-in unsubscribe mechanism, and puts your personal email address in front of everyone on your list.

Start with Mailchimp for free and move to a paid tool when you outgrow it. Do not spend time researching the perfect email platform when a clipboard and a free account will get you to 200 subscribers.

Legal Requirements You Cannot Ignore

Email marketing has real legal requirements under CAN-SPAM, and "we're a small nonprofit" is not an exemption.

Every email you send must:

Include your organization's name and mailing address — a P.O. box counts
Have a working unsubscribe link — Mailchimp and MailerLite add this automatically
Honor unsubscribe requests within 10 business days — email tools handle this if you use their platform
Use an honest subject line — no "RE: Your donation" when there was no previous donation

You cannot add people to your list without their consent. Buying a list, adding people from the phone book, or importing the roster from a Facebook group you manage — all of these can get your account suspended and expose your org to complaints. Ask first. Always.

Converting Your Facebook Followers Into Email Subscribers

This is the practical goal: take some of the audience Facebook owns and move them onto a list you own.

The conversion rate will be low — expect 5 to 10% of your Facebook followers to sign up, and that is a realistic target, not a failure. A 5% conversion on 840 followers is 42 subscribers, which is a real list you can actually use.

How to do it:

Post directly asking followers to join your email list. Explain why in plain terms: "We want to make sure you don't miss our event announcements, even when Facebook doesn't show them to you." That framing is honest and it lands.
Pin the signup post to the top of your Facebook Page so it is the first thing new visitors see.
Add the signup link to your Facebook Page's "About" section. It takes two minutes and it is permanently visible.
Include a signup link at the bottom of every event post. Not prominently — just a line at the end: "Get our announcements by email: [link]."

An Email List Only Has Value If You Use It

The orgs that build a list and then don't use it are in the same position as the ones who never built one. Supporters forget who you are after 90 days of silence.

Block 30 minutes on your calendar once a month. Send one email. It does not have to be long, polished, or designed. A plain-text email that says "Our bingo night is October 12th at the clubhouse, doors open at 6pm, $20 to play, bring a neighbor" will outperform a beautifully formatted newsletter that took six hours to produce.

The bar is lower than you think. Your audience is not comparing you to a corporate marketing department. They signed up because they care about what your org does. Show up in their inbox with something useful and they will keep opening your emails.

The Bottom Line

Facebook will change its algorithm again. It already has, several times. Organic reach for Pages has been declining for years and there is no reason to believe that trend reverses.

The orgs that will weather the next algorithm change are the ones who did not wait for it to happen. Start the clipboard at your next event. Set up the free Mailchimp account this week. Send one email before the end of the month.

You do not need 1,000 subscribers for this to matter. Two hundred people who actually open your emails are worth more than 800 Facebook followers who may or may not ever see your post.
