Every club secretary has lived this conversation. You email the whole club about the fee deadline; a fortnight later half the members swear black and blue they never received it. They're usually not fibbing — the email arrived, went straight to spam or a "Promotions" tab, and was never seen.
Club email deliverability sounds like a dark art, but it's actually a short list of understandable causes, and almost all of them are fixable in an evening. This guide explains, in plain language, why mail providers distrust club email, how the three authentication records (SPF, DKIM, DMARC) work, the sending habits that get clubs flagged, and the unsubscribe rules clubs are legally required to follow.
How spam filtering actually decides
When your email arrives at a member's mail provider, it gets scored on three broad questions:
- Is the sender who they claim to be? This is authentication — checked automatically against DNS records on your sending domain. Fail here and nothing else matters.
- Does this sender have a good history? This is reputation — bounce rates, spam complaints, whether people open your mail or delete it unread. Reputation attaches to your sending domain and builds (or erodes) over months.
- Does this specific message look like spam? Content signals — misleading subject lines, one giant image with no text, sketchy links, no unsubscribe option.
Clubs mostly fail on #1 and #2, and usually for the same underlying reason: the club's email setup grew organically out of somebody's personal account and a spreadsheet of addresses. Here's how each failure happens and how to fix it.
Cause 1: sending "as" an address you haven't authorised
The classic club pattern: the newsletter tool (or club platform) sends email with the "from" address set to northsidenetball@gmail.com or secretary@yourclub.org.au — but nobody ever told the receiving world that this tool is allowed to send as that address. To a spam filter, that's indistinguishable from forgery, because forgery is exactly what spammers do.
Since early 2024, Gmail, Yahoo and Microsoft have moved from "we prefer authentication" to "we require it for bulk senders". This single change is why many clubs noticed their open rates fall off a cliff: nothing about their email changed — the bar moved.
The fix is three DNS records on your club's own domain. In plain language:
- SPF — the guest list. One DNS record naming the services allowed to send email as
@yourclub.org.au. Your mailbox provider is on the list; so is your club platform. Anyone else claiming to be you gets marked suspicious. - DKIM — the wax seal. Your sending service cryptographically signs each message; the matching public key lives in your DNS. Receivers verify the seal — proving the message came from an authorised sender and wasn't tampered with on the way.
- DMARC — the instruction card. A record saying what receivers should do when a message fails the other two checks (deliver anyway, quarantine, or reject), plus where to send reports. Bulk-sender rules now expect you to have one, even a relaxed one.
You don't write these by hand. Any decent sending service generates the exact records and shows you what to paste into your DNS. ClubHelix's custom sending domain does this end-to-end: it issues the records, verifies them, and then signs every club email — broadcasts, receipts, notifications — from your own domain.
An unavoidable prerequisite: the club needs its own domain. If you're still entirely on a free personal address, start with how to get a club email address — you cannot properly authenticate bulk email from a personal Gmail "from" address, and mail providers increasingly rewrite or junk attempts to do so.
Cause 2: a dirty list
Reputation is the slow killer. Every time you email the whole list, the mail providers are watching what happens next:
- Hard bounces (addresses that don't exist) say you're careless with your list. Clubs accumulate these fast — members type addresses wrong on paper forms, leave the club, change providers.
- Spam complaints (someone taps "Report spam") are the most damaging signal there is. The threshold is lower than you'd think: Gmail's bulk-sender rules treat anything above about 0.3% of messages as a serious problem — that's three complaints per thousand emails.
- Sustained ignoring — messages that are never opened, year after year — gradually files you under "mail nobody wants".
Bulk-send hygiene, then, is mostly list hygiene:
- Remove hard bounces immediately. Good sending tools do this automatically; spreadsheets never do.
- Email people who expect it. The list should be current members and people who opted in — not every address the club has collected since 2015. Old lists feel like an asset; to a spam filter they're a liability.
- Never buy, borrow or merge lists from other organisations, however friendly. Recipients who don't recognise you are exactly the ones who hit "Report spam".
- Let the member database be the list. The deepest fix: when your emails go to the live member roster instead of an exported CSV, departures drop off automatically and the list can't rot. This is a structural advantage of sending through your club platform rather than a standalone tool.
Cause 3: content and sending habits that look spammy
These matter less than authentication and reputation, but they're the easy final polish:
- Send from a consistent address (
newsletter@yourclub.org.au), on a consistent rhythm. Erratic blasts from rotating addresses look bot-like. (A predictable cadence also gets more opens — see how to write a club newsletter.) - Subject lines that say what's inside. ALL CAPS, "URGENT!!!", and emoji walls trip content filters and members alike.
- Text with your images, never one big image. A message that is a single giant JPEG with no real text is a classic spam signature. Keep a healthy proportion of actual text.
- Clean links. Link to your own club website domain wherever possible. Avoid link shorteners — filters can't see through them and treat them accordingly.
- A real reply-to. No-reply addresses depress engagement, and replies are a positive reputation signal. Let members reply to a monitored role address.
The unsubscribe rules (yes, they apply to clubs)
Rather than lawyer every message, adopt the compliant baseline for all bulk email — it's also exactly what deliverability wants:
The Unsolicited Electronic Messages Act covers commercial electronic messages, and club emails promoting registrations, events, merchandise or sponsors will often qualify. It requires consent, accurate sender identification and a functional unsubscribe.
- Consent. Email people who have a relationship with the club (members and their families are fine) or who opted in. That old list of come-and-try attendees from four seasons ago doesn't age into consent.
- Identification. Every bulk message says clearly who it's from, with the club's real contact details.
- Unsubscribe. Every bulk message carries a working unsubscribe mechanism, honoured promptly. Modern bulk-sender rules go further: one-click unsubscribe (the "Unsubscribe" button mail apps show next to the sender name) is now expected from list senders, and it's a header your tool has to add — a spreadsheet-and-BCC operation simply can't comply.
One important nuance: unsubscribing from the newsletter is not the same as never being emailed. Purely transactional messages — payment receipts, registration confirmations, password resets — are a different category and should keep flowing to people who've opted out of marketing-style mail. This is why good platforms separate transactional email from broadcast email, with unsubscribe applying to the right one.
And never work around an unsubscribe ("Sandra keeps missing things so I added her back"). It's illegal, and one annoyed spam complaint from Sandra hurts delivery to every other member.
A 30-minute diagnostic for your club
Work down this list; each step catches a distinct failure:
- Send a test to a fresh Gmail account you control. Open the message, choose "Show original", and look for three verdicts: SPF PASS, DKIM PASS, DMARC PASS. Any FAIL or "neutral" → your authentication needs setting up (Cause 1).
- Check where it landed — inbox, Promotions, or Spam. Promotions is survivable (members still find important mail there); Spam is a fire to put out.
- Check your bounce and complaint numbers in your sending tool's last few campaigns. Bounces above a few percent, or any visible complaint rate, means list-cleaning time (Cause 2).
- Read your last newsletter cold. Consistent from-address? Honest subject? Real text alongside images? Unsubscribe link present and working? (Cause 3.)
- Fix in that order. Authentication first — nothing else recovers deliverability while it fails.
If you run your email through ClubHelix, most of this list is handled structurally: broadcasts go to the live member roster, bounces and unsubscribes are processed automatically, one-click unsubscribe headers are added for you, and the custom sending domain setup gets SPF and DKIM verified before the first send.
Frequently asked questions
Why do our club emails suddenly go to spam when they used to arrive fine?
Almost always because the major mail providers tightened bulk-sender requirements (from 2024 onward): senders of list email now need SPF and DKIM authentication on their own domain, a DMARC record, one-click unsubscribe, and a low complaint rate. Clubs sending from personal addresses or unauthenticated domains fell below the new bar without changing anything themselves. Set up proper authentication on a club-owned domain and delivery typically recovers within weeks.
What are SPF, DKIM and DMARC in plain English?
SPF is a guest list: a DNS record naming the services allowed to send email as your domain. DKIM is a wax seal: a digital signature on each message that receivers verify against a key in your DNS. DMARC is the instruction card: it tells receivers what to do with mail that fails the other two checks. All three are DNS records your sending service generates for you — pasting them in is a fifteen-minute job, not a technical career.
Do club newsletters legally need an unsubscribe link?
If the message has a commercial flavour — promoting registrations, events, merchandise or sponsors — then essentially everywhere the answer is yes: consent, clear sender identification, and a functional unsubscribe honoured promptly. The safe and simple policy is to include unsubscribe handling on all bulk club email. Purely transactional messages such as payment receipts and registration confirmations are treated differently and should continue even for members who opt out of newsletters.
Here the governing law is the Unsolicited Electronic Messages Act.
How many spam complaints are too many?
Gmail's bulk-sender guidance treats a complaint rate above roughly 0.3% — three per thousand messages — as a threshold where delivery suffers. For a 300-member club, a single complaint on a send is already noticeable. Keep complaints near zero by emailing only people with a real relationship to the club, making unsubscribe effortless, and never re-adding people who opted out.
ClubHelix sends your club's email the way mail providers want it sent: broadcasts to the live member list, transactional receipts and confirmations kept separate, and your own authenticated sending domain verified for you.
