How to Promote a Charity Auction and Pull In More Bids

TL;DR

• The bidding is won or lost in the fortnight before the event, not on the night.
• Build a proper guest list first, then work it channel by channel: email, social, WhatsApp, posters with a QR code.
• Preview your lots online early so people fall in love with an item before they arrive.
• Open pre-bids so the numbers are already climbing when guests walk in.
• Keep marketing rules in mind: honest asks, clear opt-outs, and let people leave your list easily.

I have spent twenty years on the mic at charity auctions, and I will tell you the thing that surprises most committees: the room is warm or cold before I ever pick up the gavel. If nobody has seen the lots, if half the tables are empty, if the regulars did not get a reminder, no amount of patter from me fixes it. Promotion is the quiet work that makes the loud night pay off.

So this is my honest, channel by channel guide to promoting a charity auction. Not theory, just what I watch actually move bids.

When should I start promoting a charity auction?

Six to eight weeks out for the save the date, two to three weeks out for the hard push. Any earlier and people forget. Any later and diaries are full.

I think of it in three waves. Wave one is “hold the date,” a short heads up so it lands in the calendar. Wave two is “here is what you can win,” where you show the lots and the cause. Wave three is “last chance,” the final week when you drive ticket sales and open pre-bids. Each wave has a job. Do not try to do all three in one email a week before, because it reads as panic and people can smell it.

How do I build the guest list?

Start with who you already have, because those people are ten times more likely to turn up and bid than a stranger. Pull together:

• Past attendees and past bidders, even from years ago.
• Your existing supporter and newsletter list.
• Local businesses you have worked with, especially any who donated lots.
• The personal contacts of every committee member. This is the big one people skip.

Ask each committee member to write down twenty names and personally invite them. A message from a friend beats a mass email every time. I have seen a single well connected volunteer fill three tables on their own.

One point on the rules here. If you are emailing or texting people to market the event, the Information Commissioner’s Office is clear that you generally need consent, and you must always make it easy for people to opt out and then respect it (ICO guidance). Charities do have some room to contact existing supporters, but the safe habit is simple: only message people who would expect to hear from you, and give a clear unsubscribe every time.

How do I use email and social without annoying people?

Email is still your workhorse. It is where the ticket link lives and where you tell the story. Keep each email to one clear job and one clear button. Wave two might be “meet three of our star lots” with photos and a line about the cause. Do not bury the ask under six paragraphs.

Social media does a different job. It is for reach and reminders, not detail. A few things that reliably work for me:

• Post a single lot at a time, with a good photo and a price teaser. One item, one story.
• Show the people, not just the products. A quick clip of a volunteer setting up beats a stock image.
• Ask supporters to share. A share from a local face travels further than anything the charity posts itself.
• Use your event hashtag and tag any businesses who donated, so they share to their followers too.

WhatsApp and community groups are underrated. A short message in the right village or club group, sent by a member rather than the charity, often outperforms a paid post. Personal beats polished.

Whatever you promise in these posts, keep it true. The Fundraising Regulator’s Code of Fundraising Practice asks that fundraising is open, honest and does not mislead (Fundraising Code). If you say a lot is worth 500 pounds, be sure it is.

Should I preview the lots online before the event?

Yes, and this is where a free platform earns its keep. When guests can browse the catalogue on their phone days ahead, they arrive having already decided what they want. Desire has time to build. On the night they are not discovering the lots, they are defending them.

I run my auctions on a free platform that puts the whole catalogue in the phone browser, no app to download, so I share one link and people are in. If you want to see how the guest side works, my how this works page walks through it, and the silent auction page shows the format most events lead with.

Previewing early also gives you a second marketing hook. “Bidding is now open” is a fresh reason to email and post again, without repeating yourself. It helps enormously if the lots themselves are the right ones, so if you are still building the catalogue, my guide to /software/ is worth a read before you promote anything.

Where QR codes and links actually help

A QR code turns a poster, a table card or the back of a ticket into a doorway. Someone points their phone, and they are looking at your lots in seconds. No typing a long web address, no friction.

Here is where I put them:

Placement	Job it does
Posters in the venue and local shops	Reach passers by before the event
Table cards on the night	Get seated guests bidding fast
Email and social posts	One tap from message to catalogue
The printed order of events	A backup route for anyone offline

The link behind the code should go straight to the catalogue, not your homepage. Every extra tap loses people. And test it, on a real phone, on the venue wifi if you can, before the doors open. I have seen a dead QR code cost a room its momentum.

How do I drive pre-bids and momentum on the night?

Pre-bids are the secret weapon. Open bidding a few days early and the numbers start climbing before anyone is in the room. When a guest sees a lot already at 120 pounds, they take it seriously. An empty item at zero says “nobody wants this.” A live one says “get in quick.”

Encourage a friendly nudge: “bidding is open, do not let the office rival outbid you.” A little rivalry, kept warm and good natured, does more than any hard sell.

On the night, momentum is about visibility and pace. Read the room, keep the popular lots moving, and call out when something is close to selling. If mobile bidding shows a leaderboard, use it. People love to see they have been overtaken, and they reach for their phones. If you want the detail on how phone bidding keeps a room active, I have written it all up in /software/ My job on the mic is to keep energy up and the cause front of mind, so nobody forgets what all this is for.

After the charity auction: the follow-up

The follow up is where you turn a good night into next year’s easy sell. Within a couple of days:

• Thank everyone, publicly and personally. Name the businesses who donated.
• Share the total raised and, if you can, what it will pay for. People gave to a cause, so close the loop.
• Thank the underbidders too. They tried, and they are your best prospects next time.
• Note what sold well and what fell flat, while it is fresh, for next year’s planning.

A warm thank you does quiet work. It keeps your list happy, keeps donors donating lots, and means your next “save the date” lands with people who already feel good about you.

Promotion is not glamorous, but it is where the money is really made. Fill the room, warm up the bidders, and my job on the night becomes easy.
