You sent the email last Tuesday. Volunteer sign-up for the annual fundraiser, deadline Friday. By Thursday night, four people had opened it. Four out of 85 members.
So you copied the same message into your WhatsApp group. Half the replies were thumbs-up emojis. Nobody actually signed up.
Friday morning, you texted the 12 people you had phone numbers for. Nine responded within the hour. Three signed up on the spot.
This isn’t a technology problem. It’s a channel problem. Every communication tool has a job it does well and a job it does badly. Most volunteer-run clubs pick one channel and blast everything through it, then wonder why half their members seem to have vanished.
The fix isn’t picking the “best” channel. It’s matching the right channel to the right message.
The numbers, unvarnished
Before we get into strategy, the raw data matters. These aren’t vibes. They’re measured.
SMS sits at the top for pure attention. Industry research consistently puts text message open rates between 90% and 98%, with most messages read within three minutes of delivery. Response rates hover around 45%. Click-through rates land between 19% and 35%, depending on the industry. When you send a text, people see it. Almost always.
Email is the workhorse everyone ignores. Average open rates for email marketing sit around 30% to 45%, though privacy features like Apple’s Mail Privacy Protection inflate those numbers by pre-loading tracking pixels. Click-through rates run 2% to 3%. Those numbers sound middling, but they’re averages across all industries, including promotional spam that nobody asked for. For a club sending relevant updates to opted-in members, the real numbers tend to run higher. Nonprofits average around 29% open rates, and associations do even better at roughly 36%. Still, nobody’s inbox is getting emptier.
WhatsApp posts numbers similar to SMS on paper, with open rates around 98% and click-through rates between 45% and 60%. But those stats come with a caveat. They’re measured primarily from WhatsApp Business API users sending transactional messages, not from group chats where your potluck reminder sits sandwiched between 40 unread messages about parking.
So which one should your club actually use? All of them, but not for the same things.
The pattern is clear. SMS gets read. Email gets skimmed. WhatsApp gets opened but easily drowned out by group noise.
What each channel is actually good at
Every channel has a personality. Use it wrong and you’re shouting into a room where nobody’s listening.
SMS: the fire alarm
Text messages work for anything time-sensitive or requiring a direct response.
Meeting cancelled tonight. Location changed. Dues reminder, last day. Emergency contact update needed. Vote closes in two hours.
These are messages where you need someone to see something right now and ideally do something about it. SMS is unmatched for this. There’s no algorithm deciding whether your message shows up. There’s no spam folder. It lands directly on someone’s lock screen and stays there.
But SMS is a terrible newsletter. The moment you start sending weekly updates or long paragraphs by text, people tune out or opt out entirely. A garden club in Virginia learned this the hard way: their treasurer started texting monthly recaps to the full membership. Within three months, a third of their members had asked to be removed from the text list. They’d burned a high-trust channel on low-priority content.
Best for: Urgent announcements, deadline reminders, last-minute changes, RSVP confirmations.
Worst for: Newsletters, detailed updates, anything over two sentences.
Email: the filing cabinet
Email is where you send things people need to reference later.
Monthly newsletters. Meeting minutes. Treasurer’s reports. Event details with maps, schedules, and packing lists. Policy changes. Renewal notices with payment links.
Nobody reads email the moment it arrives. That’s actually fine for most club communications. Email’s value comes from structure, not immediacy. You can include links, attachments, formatting, and all the details that don’t fit in a text message. Members can search their inbox later to find that potluck address or that PDF of the new bylaws.
The weakness? Volume and competition. Your club newsletter lands next to Amazon shipping notifications, work emails, and promotional noise from every service your members have ever signed up for. According to data from multiple email marketing studies, the average person receives over 120 emails per day. Your club’s update about next month’s speaker is fighting for attention against all of them.
For nonprofits specifically, email remains the primary fundraising channel. The average nonprofit generates around $1.11 in revenue per email contact. Small nonprofits actually do better, averaging $6.15 per contact. Email isn’t dead for clubs and nonprofits. But it’s not the attention-grabber it was in 2010.
Best for: Newsletters, detailed event info, official documents, anything members need to find later.
Worst for: Urgent announcements, time-sensitive requests, anything requiring a quick reply.
WhatsApp: the group hangout
WhatsApp is where casual, community-building conversation happens. It’s the digital equivalent of the conversations that happen after the meeting ends and everyone’s standing around the parking lot.
Quick polls. Photo sharing from the last event. Casual back-and-forth about where to hold the holiday party. New member introductions. The kind of ambient connection that makes people feel like they actually belong to something.
WhatsApp groups are fantastic for community feeling. They’re terrible for official business.
Why? Two reasons. First, important messages get buried. In any active group with 30+ members, a single announcement will scroll off-screen within hours, pushed down by replies, reactions, and side conversations. Second, not everyone checks group chats consistently. Some members mute WhatsApp groups the day they join them. Your critical update about the venue change sits unread under 47 messages about someone’s dog.
The WhatsApp Business API offers better tools for structured communication, with broadcast lists, automated messages, and read receipts. But the API comes with per-message costs and compliance requirements that make it overkill for most volunteer-run clubs. Regular WhatsApp groups are free but chaotic. The free WhatsApp Business app sits somewhere in between, offering basic catalog and quick-reply features without the API costs.
Best for: Community building, casual conversation, photo sharing, quick informal polls.
Worst for: Official announcements, anything requiring confirmation that everyone saw it.
What each channel costs
Cost matters for volunteer organizations running on thin budgets. The differences between channels are significant.
Email is the cheapest option at scale. Tools like Mailchimp offer free tiers for small lists (up to 250 contacts on the current free plan). Paid plans start around $13/month. For a 100-person club sending two emails a month, the cost is effectively zero. Nonprofit discounts from providers like Mailchimp (15% off) and others bring costs down further.
SMS gets expensive quickly. Most providers charge between $0.01 and $0.05 per message in the US. That sounds trivial until you do the math. A 200-member club sending four texts a month burns through 800 messages. At $0.03 each, that’s $24/month or $288/year. Not bankrupting, but real money for a group whose entire annual budget might be $2,000.
WhatsApp is free for standard groups (up to 1,024 members). The WhatsApp Business API, which offers more structured messaging features, charges per message. Marketing messages cost $0.025 to $0.14 each, depending on the recipient’s country. Utility messages run cheaper, often under $0.01. For most small clubs, free WhatsApp groups are sufficient, but you’re trading cost savings for the chaos of unstructured group chat.
The cost calculus changes based on how you use each channel. SMS is expensive per-message but high-impact when used sparingly. Email is cheap per-message but lower-impact. WhatsApp is free but unpredictable.
How to avoid becoming spam
Every channel has a line between “helpful communication from my club” and “yet another notification I don’t want.” Cross it and you lose people permanently.
The SMS rule of thumb: Don’t text more than twice a month unless something genuinely urgent is happening. Every text should pass the “would I be annoyed to get this?” test. If the answer is yes, send an email instead. And always include opt-out instructions. In the US, the Telephone Consumer Protection Act requires it, and ignoring that requirement can carry fines of $500 to $1,500 per message.
The email rule of thumb: Once a week is the upper limit for most clubs. Many do fine with twice a month. Every email should have one clear purpose. Don’t cram the newsletter, the treasurer’s report, and three event announcements into one email. Nobody reads past the second scroll.
The WhatsApp rule of thumb: Set clear group norms early. Pin the rules to the top of the chat. “This group is for club announcements and event coordination. Social chat goes in [other group].” Without norms, your announcement channel becomes a meme-sharing free-for-all within a week. Consider having two groups: one for official updates (admin-only posting), one for general discussion.
Across all channels, there’s one universal principle. Only send messages people actually need or want. The moment your communications feel like an obligation to wade through, members start tuning out. And once they’re tuned out, getting them back is nearly impossible.
The multi-channel approach that actually works
The clubs that communicate best don’t pick one channel. They use all three, with clear rules for what goes where.
A running club in Austin figured this out after years of miscommunication. They now run a simple three-tier system.
Tier 1, SMS: Rain cancellations. Route changes. “We’re meeting at the east parking lot today, not the west one.” Anything a member needs to know in the next two hours. They send maybe three texts a month, and their read rate stays above 90%.
Tier 2, Email: Weekly digest every Sunday night. Upcoming runs, volunteer opportunities, race registration deadlines, member spotlights. Everything a member might want to reference during the week. Open rate holds steady around 55%, well above industry average, because they never send more than one email per week.
Tier 3, WhatsApp: Two groups. One is admin-only for official announcements (mirroring the important parts of the email digest). The other is open for general chat, run photos, gear recommendations, and the kind of casual conversation that builds friendships.
Members know what to expect from each channel. Texts mean something important. Email means the weekly roundup. WhatsApp means community. Nobody’s getting the same message three times, and nothing critical gets lost in group chat noise.
This three-tier approach works for any type of organization. A cultural association can use SMS for event cancellations, email for monthly newsletters with festival details, and WhatsApp for food coordination and informal planning. A neighborhood association can text about emergency road closures, email the quarterly meeting agenda, and keep a WhatsApp group for neighbor-to-neighbor chat.
The key is discipline. Decide which channel does what, tell your members the plan, and stick to it.
Matching the message to the channel
Not sure where to send something? This breakdown covers the most common club communications.
Dues reminders: Start with email (include payment link). Follow up with SMS for anyone who hasn’t paid within two weeks.
Event invitations: Email for the initial invite with all the details. SMS reminder the day before.
Meeting cancellations: SMS first, immediately. Follow up in WhatsApp and email for the record.
Monthly newsletter: Email only. Never text a newsletter.
Election or vote announcements: Email with full details and voting instructions. SMS the day voting opens and an hour before it closes.
New member welcome: Email with all the getting-started info they need (meeting times, contacts, documents). Add them to WhatsApp for community connection.
Emergency or safety alerts: SMS. Full stop.
Post-event photos and recaps: WhatsApp for the photos and immediate reactions. Email for the polished recap with attendance numbers and treasurer’s update.
Does every club need all three channels from day one? No. If you’ve got 15 members and everyone’s in the same WhatsApp group, that might be enough for now. But as you grow past 30 or 40 members, the single-channel approach starts cracking. Messages get missed. Important updates drown in chatter. People stop checking because the signal-to-noise ratio drops.
That’s when a deliberate multi-channel strategy stops being a nice-to-have and becomes the thing that keeps your digitally run club functioning.
The tech keeps changing, the principle doesn’t
New channels pop up every couple of years. Discord. Slack. Telegram. Some clubs are experimenting with AI tools for administrative communication. Whatever the channel, the core question stays the same: does this message need to be seen right now, referenced later, or discussed casually?
Answer that question first, and the channel picks itself.
And as your club grows, staying on top of compliance rules around member communication becomes more important. Texting regulations, email consent requirements, and data privacy laws all affect how you can reach members. Knowing the rules before you scale up saves you from scrambling later.
The perfect communication system for your club won’t be the fanciest one. It’ll be the one your members actually read, delivered through the channel that fits the message.
Managing member communication across multiple channels gets complicated fast. Somiti gives your club a central hub for announcements, event coordination, and member contact management, so nothing falls through the cracks.
