The reel went live at 8:40 on a Thursday night. By 9:15 there were 214 unread messages, and about 190 of them said the same thing in different words: how much, is it still available, do you deliver to my city.
The seller answered the first forty by hand. Fast, friendly, real. Then she started skimming, and skimming turns into cherry-picking, because you answer the easy ones first. Which meant the person who wrote "can I get two, one in black, ready to pay now" sat at the bottom of the pile for three hours.
The campaign did fine. It also left about eleven orders on the floor, and she never found out which eleven.
That is what a DM rush actually costs you. Not the volume. The sorting.
A sale doesn't create a new problem, it exposes the one you already had
On a slow Tuesday you get thirty messages and you can hold the whole inbox in your head. You remember who asked about the beige one, who said they'd pay after payday, who is just bored and scrolling. Your memory is the system, and on thirty messages it's a decent system.
Then volume goes 8x in ninety minutes and your memory quits at the exact moment it's worth the most. Every campaign-day mess I've seen traces back to the same thing: there was no way to tell a buyer from a browser at a glance.
So accept the premise before you change anything else. You are not going to answer 300 messages well by being faster. Nobody types faster than a reel spreads. What you need is for the pile to arrive pre-sorted.
Write the answers the day before, not during
Here's the boring work that saves the campaign, and hardly anyone does it: the day before launch, sit down and write the answers to the questions you already know are coming.
You know them. They're the same every single time:
- Price, and whether the discount is already applied or comes off at checkout.
- Sizes and colours still in stock, with the ones that will sell out first named explicitly.
- Shipping cost and delivery time, split by city if that changes the answer.
- How to pay, in one sentence, with the link.
- When the offer ends, with a real date and hour. Not "soon".
- What happens if it doesn't fit, because that question blocks more purchases than price does.
Write each one the way you'd say it out loud. Then load them into whatever answers your DMs: an AI assistant, saved replies, or a note on your phone you copy from. The tool isn't the point. The point is that at 9:15pm you are never composing a sentence you could have composed at 4pm yesterday.
Prepare one more thing: the answer for whatever you're going to run out of. Write the sold-out message before the sellout, not after. I've watched sellers lose an entire evening's momentum because "sorry, gone" showed up four hours late with no alternative attached. There's a whole playbook for turning an out-of-stock reply into a saved sale, and campaign night is exactly when it earns its keep.
Three lanes, not one inbox
During a rush, stop treating your DMs as a list and start treating them as three lanes.
Lane one: ready to buy. They named a product, a size, a quantity, or asked how to pay. These get answered first, always, even if they arrived last. Everything else waits.
Lane two: a real question, not yet decided. Fit, material, delivery time, "is this okay for oily skin". These convert well, and they don't decay as fast as lane one.
Lane three: noise. "Hi". A fire emoji on your story. A heart. Worth a warm one-liner. Not worth your evening.
If you're sorting by hand, this is a five-second glance per message, and you sort into three piles before you answer anything at all. It feels slower for the first two minutes. By minute twenty it's dramatically faster, because you stop re-reading the same messages over and over.
If something is answering on your behalf, the sorting should happen automatically, and lane one should be the only thing that makes your phone buzz. The rest can sit in a queue quietly.
What to automate, and what to keep in your own hands
I'll take a side here, because sellers get this backwards constantly.
Automate the repetitive middle. Price, stock, shipping, sizing, payment link, offer deadline, order status. Those are facts. They don't need your personality, they need to be correct and instant. Handing them off isn't a downgrade in service, it's an upgrade, because a correct answer in nine seconds beats a warm answer in fifty minutes. The way conversion falls off with every minute a DM sits unanswered is not subtle, and a campaign spike is where that curve does its worst damage.
Keep for yourself: complaints, anything about money already paid, an angry customer, a wholesale or bulk request, and anyone asking something your prepared answers don't cover. On campaign day these are maybe 5% of your messages and close to half of your risk.
The rule I'd write on the wall: automate what you'd be happy printing on a sign in your shop, handle personally what you'd want to say in your own voice.
The mistake that turns a good campaign into a week of refunds
Overselling. It happens because stock lives in one place and your answers live in another, and during a spike nobody reconciles the two.
Check your numbers the morning of the launch, not the week before. If two sizes are down to single digits, say so out loud in the answer: "two left in 38". That one detail does two jobs. It creates honest urgency, and it protects you from promising something you'll have to cancel tomorrow.
A cancelled order costs you more than a slow reply ever will. The customer waited, paid, told someone, and then got a refund. That person does not come back for your next campaign.
Staff the peak, not the day
Campaign traffic doesn't spread evenly. It lands in a spike roughly 20 to 90 minutes after your post, then a second, smaller wave late at night when people are in bed with their phones.
If you have any help at all, put them on the spike. Two people for ninety minutes beats one person for six hours, every time.
The wave most sellers sleep through is the one after midnight. It's smaller, it converts well, and it usually gets answered at 10 the next morning to somebody who already bought elsewhere. The pattern in the two peaks a seller's inbox actually has holds up remarkably well on campaign days, just louder.
Practical version: decide before launch who covers which hour, and write it down. "We'll just handle it" is how the 1am wave dies.
What to say when you genuinely can't keep up
Silence is the only unforgivable option. If you're 200 messages behind, say so, in a human sentence:
"Hey! Big response tonight, I'm going through messages one by one. If you already know what you want, send me the item and the size and I'll lock it in for you now."
Two things happen. People stop assuming you're ignoring them, and a good half of them self-sort into lane one by sending you the item and size. A holding message that asks for the next piece of information is worth ten apologies.
The cleanup nobody does
The campaign ends and the inbox stays full. Most sellers scroll up, feel slightly ill, and move on.
Do this instead, within 48 hours:
- Filter to conversations where the customer sent the last message. That's your unanswered pile, and it's usually smaller than it looks.
- Answer the ones that named a product first. Some are still alive. "Sorry for the delay, still have this in 38 if you want it" recovers more sales than you'd guess.
- For anything sold out, send the closest alternative or a real restock date. An apology on its own recovers nothing.
- Write down the three questions you got most. Those go into your prepared answers before the next campaign.
That last step is the one that compounds. Every campaign should leave your answer bank better than it found it, and after three or four rounds the rush stops feeling like an emergency and starts feeling like a busy day.
The checklist, seven lines
- Answers written and loaded the day before, including the sold-out and restock lines.
- Stock numbers checked the morning of, so nothing promises what you don't have.
- Payment link tested by a real person on a real phone.
- Three lanes agreed, and one person watching lane one.
- A holding message ready for the spike.
- Coverage assigned by hour, including the late wave.
- A cleanup pass on the calendar for two days later.
It takes about an hour to set up. That hour is the difference between a campaign that sold out, and a campaign that sold out and also quietly annoyed 200 people.
If the sorting is the part that breaks under load, that's the part worth handing off. Vardast answers your Instagram, WhatsApp, Telegram and website messages from your own product information, in your own voice, around the clock, and passes the chat to you the second someone needs a human. On a normal day it gives you your evening back. On campaign night it's the reason lane one gets answered while the reel is still spreading.
