Every time someone comments “Where can I buy this?” or “How do I get the discount?” on your product post, you have a narrow window to capture that sale. Most ecommerce brands lose those buyers to friction — the link-in-bio detour, the delayed manual reply, the link tree with too many options. WilloSend removes every one of those obstacles: a follower comments your keyword, and they receive the exact product link or discount code in their DMs within seconds, while they’re still scrolling and still ready to buy.

​
Who This Is For

Ecommerce Brands & DTC Sellers

Product-based businesses with an Instagram presence and a following ready to be converted into customers.

Amazon Influencers & Affiliates

Creators promoting specific product links who need a faster, higher-converting path than a storefront or bio link.

​
What You Can Automate

CTA: “Comment SALE and I’ll DM you a 20% off code.”Delivering discount codes via DM makes them feel exclusive — like insider access, not a public coupon. Followers who receive a personal-feeling discount are more motivated to use it before it expires.
CTA: “Flash sale for the next 24 hours — comment FLASH to get the exclusive discount code.”Time-limited offers create urgency. Pair a short window with instant DM delivery and you capture buyers at the peak of their impulse. Every commenter is also boosting your post’s engagement signals, pushing it further on Instagram.
CTA: “Comment NOTIFY and I’ll DM you the link the moment we go live.”Build pre-launch interest by collecting interested buyers before your product is available. When you flip the switch on launch day, WilloSend sends the product link to everyone who opted in — turning anticipation into first-hour sales.

Personal and Direct

DMs land in an inbox — they feel like a one-to-one message, not a broadcast. That personal quality drives higher open rates and click-through rates than any link placement on your profile.

Exclusive, Not Public

A discount code delivered via DM feels like insider access. The same code posted in a caption or story feels like a generic promotion. Exclusivity drives urgency.

Zero Navigation Friction

No profile visit. No link tree. No searching for the right product. The exact link arrives in their DMs and one tap takes them straight to checkout.
Comments also amplify your post’s reach. When followers comment your keyword, Instagram’s algorithm reads that as high engagement and pushes your post to more feeds and Explore pages — giving your flash sale or product drop even more exposure at no extra cost.

​
Example Flash Sale Campaign

1

Post a product showcase Reel

Show your product in action — an unboxing, a styling video, a before-and-after. Let the product speak before you make the offer.
2

Add a time-sensitive keyword CTA

Caption: “Flash sale for the next 24 hours — comment SALE and I’ll DM you an exclusive 25% off code. ⏰”
3

Set up your automation in WilloSend

Configure the keyword and write a DM that delivers the code and the product link together:
Hey [First Name]! Here’s your exclusive 25% off code: FLASH25. Use it at checkout → [product link] 🛍️ Offer expires tonight at midnight!
See Create an Automation for the full setup guide.

Let WilloSend deliver to every commenter

Whether ten people comment or ten thousand, every single commenter receives the code instantly. No manual replies, no missed buyers, no extra work on your end.

​
Flat-Rate Pricing Means Viral Posts Don’t Cost You Extra

WilloSend charges a flat monthly rate — not per DM sent. If your flash sale post goes viral and thousands of people comment your keyword, your bill stays exactly the same. See Flat-Rate Pricing for full details.
This matters for ecommerce campaigns where viral traction is the goal. You can run aggressive CTAs, encourage sharing, and let your post spread without worrying that success will spike your automation costs.
After your campaign ends, review your results in the Analytics Dashboard to see which product posts generated the most DMs, the highest click-through rates, and — ultimately — the most purchases. Use those insights to replicate what worked in your next promotion.
