Text message reminders for silent auctions

Text is the highest-attention channel you have access to and the easiest one to ruin. A message that arrives on someone's lock screen gets read within minutes; a message that arrives too often gets the sender blocked.

The discipline is knowing which auction moments are worth interrupting someone for. There are three. Everything else is email.

Part of running a silent auction, start to finish.

Why texts are different

Email is a queue people process when convenient. Text is an interruption people handle immediately. That difference is worth almost nothing for announcements and worth a great deal for anything time-critical.

A silent auction has exactly three time-critical moments, and they are the three where a delayed response costs money: being outbid with time left to respond, bidding about to close, and an invoice sitting unpaid while enthusiasm decays.

Use text for those. Use email for the rest.

The three moments

Outbid alerts do the real work

If you only enable one automated message in your entire auction, make it this one.

Here is the mechanism. Once someone has bid on an item, they have mentally claimed it — being outbid registers as losing something they had rather than failing to win something they wanted. That asymmetry is well documented in behavioural research on loss aversion, and it is what turns a single bid into a bidding war.

But it only fires if the bidder finds out in time. A supporter who checks their email on Sunday and discovers they were outbid on Thursday has had no opportunity to compete. An outbid text closes that gap to minutes.

Practically, this means the auction runs its own competition without anyone on your committee doing anything. 32auctions sends automated text and email notifications, including outbid alerts, as bidding happens. More on the underlying behaviour in the psychology of auction bidding.

Closing alerts

One text, in the final hours. Not three.

Urgency is real and it is the reason the last hour of an auction produces a disproportionate share of the total. But urgency delivered repeatedly stops being urgency and becomes noise — and the third message is the one that gets you muted before the message that mattered.

Include the closing time with the time zone, and a direct link. On 32auctions, all participants are automatically notified when 24 hours remain, so plan your own message around that rather than duplicating it — a text in the final two or three hours complements it well.

See auction closing strategy for how the end of your auction should be designed.

Winning and paying

The gap between winning and paying is where money leaks out of auctions, and it opens the second bidding stops.

A winner who receives a text with their invoice and a payment link, while they are still pleased about winning, frequently pays within minutes. The same winner reached three days later by email is materially less likely to pay at all. See recovering unpaid invoices and auction checkout.

One payment reminder by text is reasonable. Beyond that, switch to a personal message or a phone call — which converts better anyway.

Consent and the rules

Sending text messages to mobile numbers is regulated in the United States, principally under the Telephone Consumer Protection Act, and the rules are stricter than most volunteers expect. This is general information rather than legal advice — if you are running texting at scale, take advice.

The practical version:

• Get consent, and get it explicitly. A phone number collected for one purpose is not consent to market to it. Ask at registration, clearly, and record it.
• Say what they are signing up for. "Outbid and closing alerts for this auction" sets an expectation you can meet.
• Make opting out obvious and instant, and honour it immediately.
• Keep it transactional. Alerts about a bidder's own activity sit very differently from broadcast marketing, both legally and in how they are received.
• Do not import a list. A spreadsheet of phone numbers from a past event is not a consented list.

Using a platform's built-in notifications rather than a volunteer's personal phone also gives you a record of consent and delivery, which matters if anyone ever asks.

Writing a text that works

• Say who it is from, immediately. An unidentified number asking someone to click a link reads as a scam.
• One piece of information, one link. Nothing else.
• Put the specific item in it. "You've been outbid on the cabin weekend" beats "you've been outbid."
• Keep it short enough to read on a lock screen without opening it.
• State the time zone on anything with a deadline.
• No emoji chains, no all caps. They read as spam and get filtered.

Text mistakes

• Texting announcements. Not urgent, so not a text.
• Multiple closing reminders. One. The rest cost you the audience.
• No sender identification. Reads as a scam and gets ignored or reported.
• Importing old phone numbers. Not consent, and it exposes you.
• Texting from a volunteer's phone. No consent record, no opt-out handling, and the volunteer gets the replies for a year.
• Omitting the time zone. Entirely avoidable complaints.
