Work backwards from there and from December 31:
​

• Early October — a twelve-week campaign launches
• Late September — everything must be finished, tested and approved
• December 1 — GivingTuesday
• December 29–31 — the highest-yield 72 hours of the year

​
Which puts roughly four weeks between today and the point where you should be executing rather than building.

The email sequence, written and loaded.

Not planned. Written, proofed, and sitting in your email platform as scheduled drafts.

Guidance across the sector converges on seven to ten emails between GivingTuesday and December 31, with at least weekly sends through the run-up and no fewer than three in the final week.

If that number makes you uncomfortable, it is worth knowing that unsubscribe rates during year-end tend to run lower than the rest of the year — in the region of 0.2–0.3% against a more typical 0.5% — because donors expect to be asked in December. The fear of over-asking is usually more expensive than the asking.

A workable shape:

• A gratitude email around Thanksgiving with no ask in it at all
• The GivingTuesday appeal on December 1, with the match front and centre
• A mid-December impact update
• Three closing emails between December 29 and 31, spaced roughly 48 hours, 24 hours, and a few hours before midnight

Write all of them in September. Writing the December 31 email on December 31 is how you end up sending something forgettable during the single most valuable hour of your year.

The landing page, published and indexed.

This is the piece that gets left until November, and it is the one that most needs the lead time.

A donation landing page published on December 1 has had no chance to be crawled, indexed, or tested. Publish it in September. Link to it from your homepage. Let search engines find it, let your analytics collect a baseline, and let real people click it while the stakes are low.

While it is live and quiet, check the things nobody checks in December: that it loads fast on a phone on cellular data, that the form does not demand information you have no use for, that the confirmation email arrives promptly and reads like a human wrote it, and that a failed card produces a message a donor can act on.

The segments, as actual lists.

In August these were a plan. In September they need to be real lists in your CRM or email platform, with the counts written down: current donors, lapsed donors, monthly givers, and non-donors on your list.
Knowing you have 412 lapsed donors rather than "a few hundred" changes what you write to them and what you expect back.

The story, edited.

You gathered it in August. September is for cutting it down. One story, told in a form short enough to survive an email and strong enough to carry a landing page. If it needs three paragraphs of setup before it lands, it is not the story.

The match, confirmed in writing.

Not "interested." Confirmed — the amount, the conditions, the deadline, and permission to use the funder's name.

A match that exists only in a conversation from August is a match that can quietly evaporate in November, usually at the point where you have already written the email that references it.

GivingTuesday raised an estimated $4.0 billion in the United States in 2025, from roughly 19.1 million donors.

It is genuinely large, and it is also the single most competitive inbox day of the nonprofit year. Every organization your donors support will be asking on the same Tuesday.

Treat it as the opening of your campaign rather than the whole of it. The revenue that actually decides your year arrives four weeks later, in the last three days of December. A GivingTuesday result that looks disappointing on the day frequently looks fine by January 2 — provided somebody kept communicating in between.

Two exercises worth doing before the month ends.

Send yourself the sequence. Add yourself and a colleague to a test segment and run the whole thing. Read it as a donor would, in order, on a phone. You will find broken merge tags, a subject line that repeats, and at least one email that assumes the reader saw the previous one.
​
Give yourself $50. Complete a real donation on your own page, on a phone, on cellular. Then look at what arrives — the receipt, the thank-you, the tax language, the timing. Refund it afterwards if you need to. It is the cheapest fifty dollars you will spend this quarter.

The failure mode that shows up in December is rarely a bad plan. It is a plan where nobody is quite sure who presses send.

Before September ends, write down one name against each of these: who approves final copy, who schedules and sends, who monitors the inbox for replies and bounced cards, who watches the numbers daily in the final week, and who is available on December 31.
​
That last one matters more than it sounds. The highest-yield hours of your year fall on a day when most people are not working.

October, November and December are execution months.

​There is very little room in them for building things, because the campaign is already running and every hour goes to responding rather than creating.​

September is the last month where you can make something carefully. What you finish now is what December has to work with.
