Flows run on their own. Campaigns are the layer you send by hand. This page is how I run that layer without training the list to wait for a discount or mailing it into the spam folder.
Most brands get one of two things wrong with campaigns. Either it's all campaigns and no flows, which leaves the highest-RPR automated revenue sitting untouched. Or it's all promo and no value, which teaches the list to wait for the next 20% off and ignore everything in between. The calendar fixes both. It sits on top of your flows, it runs on a fixed rhythm, and it splits deliberately between value and selling.
If your flows are already live, this is the layer that decides whether your list compounds into an asset or degrades into a liability you slowly mail to death.
This whole page is authored operator guidance, not measured benchmark data. The cadence numbers, the value-to-promo ratio, the calendar grid, and the segmentation rules are practical starting points I'd hand a brand on day one. Treat them as defaults to tune against your own list, not laws.
I start most brands at 2 to 4 campaign emails a week. Below 2, you go invisible. The list forgets who you are, your sender reputation goes stale, and when you finally do send, the unsubscribe rate climbs because people don't remember opting in. Above 4, you need real content and a genuinely engaged list to justify it, or you're just mailing your tired segment into the junk folder.
The right number is a function of two things: how much you actually have to say, and how engaged your list is. A brand with a real content engine and a deep 90-day-engaged segment can send near-daily to that segment and be fine. A brand with thin content and a quiet list should sit at 2 and earn the right to scale.
The mistake is picking the number off a revenue target instead of off engagement. Sending more does not linearly make more money. Past the point your engaged segment can absorb, every extra send taxes deliverability for the whole program, including the flows that pay the bills.
Scale volume the way you'd scale ad spend. Step it up gradually, watch the leading indicators (click rate, complaint rate, unsubscribe rate), and don't jump from 2 to 6 in a week.
Aim for roughly 60 to 70% value and 30 to 40% promo. (Authored guidance, not a measured benchmark.)
Value means education, story, founder content, how-to, behind the scenes, social proof, UGC roundups, use-case content. Promo means the email exists to move product behind an offer or a hard push.
The reason for the split isn't virtue. A list trained to expect value opens your emails by default. A list trained to expect promos only opens when there's a code, so your full-price sends get ignored and your discount sends quietly eat margin. The value emails are what keep the promo emails landing in the inbox and getting opened.
Here's the ratio in practice across a month at 2 to 3 sends a week, roughly 10 sends:
| Send type | Count in a ~10-send month | What it's doing |
|---|---|---|
| Value / education / story | 6 to 7 | Keeps open and engagement high so the promos land |
| Promotional | 3 to 4 | Moves product. The part that erodes margin if you overdo it |
If you're sitting under 60% value right now, you don't have a sending problem. You have a content problem. Fix the content supply first. The calendar can't run on promos alone.
