Long before “growth stack” became standard language, integrated campaign systems were already connecting physical mail, response tracking, donation funnels, campaign cost, and donor records.

In late-1990s and early-2000s work supporting March of Dimes marketing efforts with Grizzard and Duniya Technologies, Zyel founder Chason Wetter helped build technology around that connection. This is founder history before Zyel—not a claim that March of Dimes was a Zyel client.

Give every campaign a cost identity.

A campaign cannot be compared if creative, list, production, postage, media, and technology costs live in unrelated summaries. The first engineering job is to give the campaign and its variants stable identifiers.

Those identifiers should follow a response into the donation path and donor record. That continuity turns “the mailing performed well” into evidence that can be profiled by campaign, audience, channel, and outcome.

02

Measure the funnel, not only the gift.

The donation is the final event, but engagement begins earlier. A tracked response, landing-page visit, form start, completed gift, repeat gift, and later communication each reveal a different part of the relationship.

Instrumenting those stages helps separate a weak offer from a broken experience. It also makes optimization more responsible: teams can improve the point where people struggle instead of simply increasing volume.

  • Campaign and creative identifiers
  • Response and engagement events
  • Donation completion and exception reasons
  • Cost allocation at campaign and donor level
03

Calculate acquisition cost with declared rules.

Cost per acquired donor looks simple: eligible campaign cost divided by new donors attributed to the campaign. The hard part is declaring what counts in the numerator, how a donor is considered new, which attribution window applies, and how shared costs are allocated.

The formula becomes trustworthy when those rules are explicit and versioned. Without them, a dashboard can display a precise number that different teams interpret differently.

Carry the lesson into modern channels.

Today the response may arrive through a QR code, paid social link, email, search result, or partner portal. The engineering principle is unchanged: stable identity, event continuity, cost context, declared attribution rules, and a path from summary metrics back to source evidence.

Modern analytics adds speed and volume. It does not remove the need to define the business meaning of the measurement.

Attribution becomes useful when a dollar of campaign cost can be followed into a declared, reviewable acquisition rule.
