Start at once every two weeks and move to weekly once you can sustain it without the quality dropping. Weekly is the sweet spot for most small businesses. The number matters far less than consistency, because an unpredictable sender is forgotten between sends and then reported as spam when they reappear.
The right cadence is the one you can still hold in your busiest month.
Why less often is not safer
Emailing rarely feels respectful and usually performs worse.
A list that hears from you quarterly forgets who you are. The next email arrives as a surprise from an unfamiliar sender, which produces exactly the complaints and unsubscribes the low frequency was meant to avoid.
Mailbox providers also read inconsistency as a risk signal. Regular sending to an engaged list builds reputation; sporadic bursts do not.
The signals that you are sending too much
Frequency is wrong when the numbers move in a specific pattern, not when it feels like a lot.
- Unsubscribes rising while open rate stays flat, which means content is fine and volume is not
- Open rate declining steadily over several sends rather than fluctuating
- Complaint rate creeping up, which is the serious one
- Your own reluctance to send because you have nothing to say, which is the earliest signal of all
The real constraint is having something to say
Almost every frequency problem is a content problem wearing a scheduling costume. Nobody unsubscribes from an email they were glad to get.
Before increasing frequency, check whether you have enough genuinely useful material for the higher rate. If the extra sends would be padding, the extra sends will cost you subscribers.
Repurposing is the honest way to raise frequency: the same underlying work, sent in a different useful form, is not padding.
Let people choose
A preference option in your emails lets someone move to a lower frequency instead of leaving entirely, and a reduced subscriber is worth considerably more than a lost one.
Two options is enough. More than that is a form, and forms get abandoned.
Different email types have different limits
Do not average across everything. A welcome sequence can send several times in the first fortnight because the person just arrived and is most interested then. Transactional email has no frequency limit because it was requested by an action.
The cadence question applies to broadcast marketing email specifically, and mixing the types in one count will lead you to the wrong conclusion.
How to change cadence safely
Move gradually and tell people. Going from monthly to weekly overnight generates complaints even among people who like you, because it reads as a change in the deal they agreed to.
Announce it, give a reason, offer the lower frequency option in the same email, then step it up over a few weeks. Watch complaints rather than unsubscribes, since complaints are the number that damages your ability to reach anyone.
Common questions
- How often should I email my list?
- Start every two weeks and move to weekly once you can sustain it without quality dropping. Weekly suits most small businesses, and consistency matters far more than the exact number.
- Can I email too little?
- Yes, and it is riskier than people think. A list that hears from you quarterly forgets who you are, so the next email arrives as a surprise from an unfamiliar sender and produces the complaints the low frequency was meant to avoid.
- How do I know I am sending too often?
- Unsubscribes rising while open rate stays flat means content is fine and volume is not. A steadily declining open rate over several sends and a creeping complaint rate are the other two signals.
