Beyond the big three email flows

Every address on your list cost you something: an ad click, a discount, a moment of trust. It is the only audience you own rather than rent, and in most stores it goes quiet within weeks of the first order.

You already know the three flows. Welcome, abandoned cart, win-back. If you do not have them, build them this week and stop reading. If you do have them, they are almost certainly the ceiling you are stuck at, because the leverage is not more flows. It is who gets them, which two you skipped, and what you are measuring.

The baseline, briefly

• Welcome, 2 to 3 emails. First one immediately, while intent is highest. Introduce the brand, earn trust, then make the offer. Not all three in the first email.
• Abandoned cart, 2 emails. First at about one hour, second at about 24 hours. Most of the recoverable revenue is in that first window, while the tab is arguably still open.
• Win-back, 1 email. At 60 to 90 days of no purchase. Lead with something new, not a discount. Discount-led win-backs teach people to lapse on purpose.

That is table stakes. Everything below is where the actual money is.

Segmentation: stop sending one email to everyone

A first-time subscriber who has never bought and a three-time buyer who spent $600 last quarter should not receive the same welcome, the same cart nudge, or the same win-back. They have different objections and wildly different value, and one message cannot serve both without being weak for each.

You do not need a complicated segmentation model. Split on behaviour you already have:

• Never purchased. The job is trust. Social proof, the guarantee, the objection your reviews keep raising. Not urgency.
• Bought once. The job is the second order, which is the hardest one in ecommerce and the one that decides your LTV. Make it about the natural next product, not a random discount.
• Repeat buyers. The job is frequency and basket. These people already trust you, so stop selling and start recommending.
• Lapsed VIPs. Highest value, most at risk, and the one segment where a personal note from a human outperforms any automation.

Segment the flows you already have before you build new ones. The same three flows, split four ways, will beat six unsegmented flows almost every time.

The two flows most stores skip

These are not exotic. They are just less famous than the big three, and both trigger on signals you already collect.

1. Post-purchase replenishment. If your product runs out on a predictable cycle, the reminder should arrive a little before it does. Take the median days between first and second order for that product and send at roughly 80 percent of it. This is the single easiest repeat-revenue flow to add and most consumable brands do not have it.
2. Browse abandonment. Someone viewed a product two or three times and never added to cart. That is real intent with an unanswered objection. One email, no discount, addressing the objection your reviews say people have about that product. Lower volume than cart abandonment, and it reaches people earlier, before they have decided against you.

Measure revenue per recipient, not opens

Open rate stopped being a real metric when Apple Mail Privacy Protection began pre-fetching images, which inflates opens for a large and unknowable share of your list. Steering by opens now means steering by a number that partly measures which mail clients your subscribers use.

This one number ends most email arguments. It rewards relevance and punishes blasting, it is comparable across sends of different sizes, and no privacy feature can inflate it. Track it per flow and per segment, and let it decide what you build next.

Two things that quietly cost you

• Sending to unengaged subscribers. Mailing people who have not opened in six months hurts deliverability for everyone else on your list. Sunset them. A smaller list that reaches the inbox is worth more than a big one in spam.
• Discounting by reflex. Every automatic discount trains people to wait for it. Use the objection first and the discount only when nothing else moves.

Where Wizzy comes in

Flows are not hard to build once. They are hard to keep good: the segments drift, the copy goes stale, the replenishment window changes when your product mix does, and nobody has time to re-cut the analysis every month. Wizzy writes and runs the flows in your voice, segments them by real purchase behaviour, adds the replenishment and browse-abandonment flows most stores never get to, and tunes subject lines and timing against revenue per recipient rather than opens.
