# Instagram DM automation for ecommerce brands

Every “how much?” under an ad gets a price, a link and a code before they scroll away. Your ad spend stops leaking into an inbox nobody has time to open.

## The problem

- **Ad comments are the cheapest leads you will buy.** Someone asking the price under a paid post is the warmest traffic of your week, and they are waiting on a person who is asleep, in a meeting, or three hundred comments behind.
- **The same eight questions, all day.** Sizing, shipping, restocks, returns. Answering them by hand is a job, and the person doing it is not doing anything else.
- **Codes die in the comment thread.** A launch code buried under 200 replies is a promotion nobody redeems and a campaign you cannot attribute.

## How it works for you

1. **Trigger on the ad, not just the post.** Comments on sponsored posts fire the same automation as organic ones, so paid traffic gets answered at the speed you paid for.
2. **Answer with the thing that closes.** Price, product link, size chart, discount code, all attached to the DM, not to a bio page they have to go looking through.
3. **Pick the conversation back up.** SendBack reprocesses the comments that were skipped or delayed during a spike, so a warm lead does not go cold because of your own traffic.

## Features that matter most

- **Sponsored ad comments.** The comment section under a paid post becomes a working funnel instead of a support queue.
- **Global Triggers.** Set “shipping” or “restock” once and it answers across every post, reel, story and inbox message.
- **SendBack.** Recovers the interactions that got skipped when a post ran hot.
- **Smart Menu.** Up to four quick-reply buttons in the inbox: shop, sizing, track my order, talk to a human.
- **Suggest More.** Recommends the next product in the same conversation, while the card is still out.
- **Flow Automation.** Qualify, branch and route the conversation instead of sending one message and hoping.

## Automations worth building first

- A price trigger on the ad you are spending the most on.
- A Global Trigger for shipping and returns, live on everything at once.
- A launch code that only goes out in the DM, so redemptions are traceable.
- Email capture on first purchase intent, synced to your email tool.

## Which plan

400,000 DMs and five accounts, sized for campaign weeks where the comment volume is the entire point.

## Frequently asked questions

### Does it work on comments under sponsored posts?

Yes. Ad comments are treated like any other comment, so the same keyword and the same DM work on paid and organic posts without a second setup.

### What happens when a campaign spikes?

The Excess DM Queue stores and processes high volumes rather than dropping them, and SendBack goes back for anything that was skipped or delayed. Plans are sized by monthly DMs, so check the number on the pricing page against your busiest month, not your average one.

### Is this safe for my account?

ReplyRep runs on Meta's official Instagram API. We never ask for your password, we stay inside Meta's rate limits, and we only message people who interacted with you first, which is the whole difference between automation and spam.
