How often to email, without burning the list.
Email too little and they forget you; too much and they unsubscribe. The right cadence depends on your goal and how engaged your list actually is. Tell us those, and we'll recommend a weekly and monthly sending rhythm, and flag if your current pace is heading for fatigue.

Sensitivity · engagement earns frequency
Recommended cadence by how engaged your list is
| Engaged share | Sends / week | Sends / month |
|---|---|---|
| 10% | 2 | 8 |
| 20% | 2–3 | 8–12 |
| 30% | 2–3 | 8–12 |
| 40% | 2–4 | 8–16 |
| 50% | 2–4 | 8–16 |
| 70% | 2–4 | 8–16 |
A list that opens earns the right to hear from you more often. As engagement climbs, the safe cadence rises with it — and a disengaged list punishes the same volume with unsubscribes.
Your move
Cadence is the easy part. Having something worth opening is the work.
Recommended: 2–3/week (8–12/month) for a e-commerce / lifecycle program at 30% engagement.
The right frequency only matters if each email earns its place in the inbox. I build email programs people actually want, the cadence, the segments, and the content that keeps them opening. Tell me about your list and I'll show you, free, where I'd start.
Plain English
Frequency is a relationship, not a setting.
There's no universal 'right' number of emails. The correct cadence is the most you can send while still being wanted, and that line depends on two things: what you're trying to do (a weekly newsletter and an ecommerce promo calendar live at different tempos) and how engaged your list is. A list that loves you tolerates more; a cold one punishes the same volume with unsubscribes and spam complaints.
Send too little and you pay the forgetting tax: subscribers don't recognize you, opens fall, and your hard won list quietly decays. Send too much, especially to disengaged people, and you trigger unsubscribes, spam flags, and deliverability damage that hurts every future send. The goal is the sweet spot where frequency builds the relationship instead of taxing it.
This calculator recommends a weekly and monthly cadence from your goal and engagement, projects how many total emails that means across your list, and warns you if your current pace exceeds the healthy ceiling. The deeper lever, though, is segmentation: email your engaged subscribers often and your dormant ones rarely, and you get the volume without the fatigue.
The formula
Right cadence = goal's base rhythm × engagement adjustment
An ecommerce list (base 2 to 4/week) with 30% engagement leans to the lower middle of that range; the same list at 50%+ engagement can run the top. A nurture sequence sits at 1 to 2/week. We start from the goal's rhythm and pull the ceiling down when engagement is weak, because a tired list can't absorb a hot pace.
Cadence by goal
Sensible starting rhythms by what you're trying to achieve. Treat these as defaults to test against your own unsubscribe and engagement data, your list is the real authority:
| Goal | Cadence | Why |
|---|---|---|
| Newsletter / brand | 1 / week | One reliable, valuable send a week beats sporadic bursts. |
| Lead nurture | 1 to 2 / week | Stay top-of-mind without crowding the inbox. |
| Sales / promotion | 2 to 3 / week | Promo windows tolerate more — outside them, ease off. |
| E-commerce / lifecycle | 2 to 4 / week | Engaged buyers accept frequent, relevant sends; segment the rest. |

Reading your cadence
You're over the recommended ceiling.
You're risking fatigue, unsubscribes, and spam complaints. Pull back overall, or, better, keep the volume only for your most engaged segment.
You're well under the floor.
You're leaving relationship and revenue on the table. Subscribers forget brands they rarely hear from. Add a consistent weekly touch.
Low engagement, high frequency.
The worst combination. Sending hard to a cold list accelerates decay and damages deliverability. Cut frequency to the dormant group and win them back before you resume.
High engagement, low frequency.
You can safely send more to this group. An eager list is an asset you're under using, test stepping up cadence and watch the metrics.
Unsubscribe rate above ~0.5% per send.
A clear over frequency or relevance signal. Reduce cadence, tighten targeting, and make every send earn its place in the inbox.
How to find your right frequency
01Segment by engagement
The single biggest unlock. Email actives often and dormants rarely, you get the volume and revenue without burning the whole list.
02Let subscribers choose
A preference center where people pick cadence and topics dramatically cuts unsubscribes. The ones who opt for more are your best customers.
03Watch unsubscribe and complaint rates
These are your speedometer. Climbing rates mean you're going too fast for the value you're delivering. Adjust before deliverability suffers.
04Earn the right to send more
Frequency tolerance rises with value. The more useful each email is, the more often you can show up without wearing out your welcome.
05Match cadence to the calendar
Promo windows (launches, holidays) justify more sends; quiet periods justify fewer. Flex frequency with what you actually have to say.
06Test, don't guess
Run a higher cadence test on a segment and compare revenue, unsubscribes, and complaints against a control. The data beats any rule of thumb.
The vocabulary
- Send frequency
- How often you email a subscriber, the lever that balances staying top of mind against fatigue.
- Engagement rate
- The share of your list that regularly opens or clicks. The biggest factor in how much you can safely send.
- Unsubscribe rate
- Opt outs per send. Above ~0.5% is a sign your frequency or relevance is off.
- List fatigue
- Declining engagement caused by over mailing, falling opens, rising unsubscribes, and spam complaints.
- Segmentation
- Splitting your list so you can send different cadences to engaged vs. dormant subscribers.
Send frequency questions, straight answers
It depends on your goal and engagement, but common starting points are: one weekly send for a newsletter or brand, one to two for lead nurture, two to three for sales driven programs, and two to four for engaged ecommerce lists. This calculator tailors that to your engagement and warns you if your current pace risks fatigue.
