Handwritten mail, run under your name

The argument you will make to the client

Not ours - the industry’s. The Association of National Advertisers has run a response-rate series for two decades, and the gap between a letterbox and a feed has been the consistent finding.

Read that carefully before you put it in a deck, because the units are not the same across the rows. A mail response and a display click are different events, and the comparison is directional rather than like-for-like. An agency that presents it as “mail is a hundred times better than display” will be caught out by the first client who reads the footnote.

These are United States figures, self-reported by the marketers who ran the campaigns, and there is no equivalent Australian series. Treat them as the shape of the thing rather than a forecast of your result - the honest use is to compare channels and list types against each other, not to predict a number for your campaign.

Where the real leverage is, and it is not the pen

The same series consistently finds the biggest single variable is who you mail, not what you send them.

This is the most useful thing on the page for an agency, because it is an argument for spending the budget on data work before production. A client with a neglected customer file and a plan to buy a cold list has the priority backwards, and the benchmark says so.

Personalisation compounds it - 2–3× the response of a generic equivalent, the multiple most often reported, not a guarantee. Every piece we write can carry different merge content, so a run of five thousand can be five thousand different letters without a change in the production cost.

What we are not going to claim

That handwriting causes those numbers. It does not - the figures are for direct mail as a channel, and the study does not isolate the pen. What handwriting plausibly changes is whether the envelope gets opened rather than triaged with the windowed ones, which is a real effect at a specific point in the funnel and a smaller claim than the one you will hear from suppliers who have not read the report either.

Our fuller position on what the evidence does and does not support is worth ten minutes before you build a pitch on it. It will make you harder to challenge in the room.

How it works in practice

• You brief, we quote. Volume, word count, envelope or not. A trade schedule rather than the published rates.
• Stock is yours. Your client’s paper and envelopes, or your printer’s. We write on what arrives.
• Sign-off before production. We confirm the job with you before anything runs, and can send a written sample where the job warrants it.
• Finished work returns to you, or goes to your client under your name.

You send them, not us

The default is that the written pieces come back to you unposted. Agencies almost always want it that way, and the reason is rarely the postage rate:

• The mail date is part of the plan. If the letter is supposed to land two days before the calls start, or the week the campaign goes live, that timing is yours to set. A supplier lodging on its own schedule breaks the sequencing you sold.
• The client signs off on the physical thing. Not a proof - the actual box. It is a good meeting and it is the last moment a name can be fixed.
• The letter is one piece of a pack. If a brochure, a sample or a gift goes in with it, you are assembling that, so you need the pieces loose.
• The postage account may be the client’s. Where it is, lodging it through them is cheaper than anything we would quote and keeps the spend on their ledger rather than through your markup.

Say at the quote stage whether you want them sealed or left open, and whether they should come back in list order. Both are straightforward during the run and irritating afterwards.

We will lodge for you where you would rather not touch it - the calculator has both options. Postage is quoted separately either way, once the finished piece exists, because weight and format decide the rate.

Where this does not suit an agency

If your client’s contribution per conversion is fifteen dollars, the arithmetic does not work at any volume and we would rather say so now than after a campaign. Handwritten mail earns its cost where a single response is worth hundreds - a listing, a policy, a case, a lapsed high-value donor. Run that calculation before the creative.

The calculator gives you the cost side for any combination, and it does not ask for an email address, so you can put a number in a deck this afternoon.
