How to build your Instagram audience

What is an Instagram audience — and why is there no search box?

Your Instagram audience is simply the list of people you want your DM campaign to reach, each one identified by their Instagram handle (their @username). WarmySender reaches exactly the people you add — it follows, views, likes, comments, and messages the handles on your list, and no one else.

Unlike LinkedIn, Instagram outreach in WarmySender has no in-app prospect search. You won't find a "search Instagram for prospects" box, because Instagram's platform doesn't allow prospect discovery through connected tools the way LinkedIn does. Instead, you bring the handles you already have — from your own research, a spreadsheet, an export from another tool, or your existing contacts.

This is a feature, not a limitation. Bringing your own, hand-picked audience means you reach people you've genuinely chosen to contact, which reads as real outreach rather than a scrape — and that keeps your Instagram account safer. Account safety always comes first on Instagram, because a restricted account is hard to get back. See how Instagram outreach keeps your account safe for the full picture.

Instagram is an add-on channel that sits under WarmySender's Multichannel pillar. WarmySender is a 4-pillar outreach platform — Cold Emailing, Email Warmup, LinkedIn Outreach, and Multichannel — and the same audience you build here can be reused across your Instagram, email, and LinkedIn outreach.

Two ways to build your audience

There are two ways to get Instagram handles into WarmySender. Pick whichever fits how you already keep your list:

Method A — Upload a CSV and save it as a list

Best when you already have your prospects in a spreadsheet, or you want a reusable, named list you can attach to more than one campaign. You upload a CSV on the Prospects page, map the column that holds each person's Instagram handle, and save everyone to a list. That list is then ready to use in any Instagram campaign.

Method B — Paste handles into the campaign wizard

Best for a quick, one-off audience. When you're building a campaign, the Prospects step lets you paste @handles directly — one per line — and WarmySender turns them into your audience on the spot, without a separate upload.

Both methods build the same kind of audience. Method A gives you a saved, reusable list; Method B is the fastest path when you just want to launch. You can also combine them — start from a saved list and paste a few more handles in the wizard.

Method A: upload a CSV and save it as a list

This is the most common way to build a sizeable, reusable audience. Here's the flow from spreadsheet to saved list.

What columns to include

Your CSV needs one column that holds each person's Instagram handle, plus whatever you'd like to personalize your messages with. A simple, effective set of columns is:

first_name

The person's first name. Used to personalize your DM — for example Hi {{first_name}}. Optional but recommended.

last_name

The person's last name. Optional; handy for context or personalization.

instagram_username

The person's Instagram handle. This is the column that makes a prospect reachable on Instagram. You can enter it as a plain handle (@janedoe or janedoe) or as a full profile link (instagram.com/janedoe or https://instagram.com/janedoe) — WarmySender reads all of these the same way.

You can include any other columns too — company, title, city, or your own custom fields — and use them as personalization variables in your DMs and comments, exactly like the variables described in the personalization guide. The one column that matters for Instagram is the handle column.

Example CSV

A minimal CSV looks like this — a header row, then one row per person:

As the example shows, the handle column can mix formats — an @handle, a bare handle, or a full instagram.com/... link all work. As plain text, that same file reads: a header row of first_name, last_name, instagram_username, then rows like Jane, Doe, @janedoe and Aisha, Khan, instagram.com/aisha.khan.

Step by step

1. Go to the Prospects page and choose Import (upload a CSV).
2. Select your CSV file. WarmySender reads the header row and shows a mapping screen so you can match each column to the right field.
3. Map your handle column to Instagram Username / URL. This is the step that makes each prospect reachable on Instagram — map instagram_username (or whatever you named your handle column) to it. Map first_name and last_name to their fields too, and map any extra columns to custom fields if you want them for personalization.
4. Save everyone to a list. Give the list a clear name (for example "Instagram — creators Q3") so you can find and reuse it. Saving to a list keeps this batch organized and makes it selectable in the campaign builder.
5. Open Instagram → Campaigns, create a campaign, and on the Prospects step choose your saved list as the audience. Build your sequence and launch — see how to build an Instagram DM campaign.

Because the list is saved, you can reuse it in more than one campaign, add more people to it later, and keep your imported batches tidy. The Instagram handle stays on each prospect, so the same people are ready whenever you want to reach them on Instagram again.

Method B: paste handles into the campaign wizard

When you just want to launch quickly with a handful of people, you don't need a CSV at all. Build a campaign and paste the handles right in.

1. Go to Instagram → Campaigns and click New campaign. Name it and pick the connected Instagram account it should run from.
2. On the Prospects step, choose the option to paste handles, then type or paste your @handles — one per line. For example, one line reading @janedoe, the next @marcorossi, and so on. A bare handle or an instagram.com/... link works too.
3. WarmySender turns those handles into your audience for this campaign on the spot — no separate upload or list needed.
4. Build your sequence (Follow, Like, Send DM, with Waits and an If Replied branch), then review and launch.

Pasting is the fastest path to a running campaign. If you'd rather keep the audience for reuse, use Method A instead and save it as a list — pasted handles power the campaign you're building right then.

What happens to prospects without an Instagram handle?

A prospect can only be reached on Instagram if they have a handle. If a prospect on your list has no Instagram handle, WarmySender simply skips them for the Instagram steps of a sequence rather than getting stuck or erroring — the campaign keeps running for everyone who does have a handle.

This matters most when you reuse a mixed list. If you attach a list you originally built for email or LinkedIn to an Instagram campaign, the people on it who happen to have an Instagram handle are reached on Instagram, and the people who don't are quietly passed over for the Instagram steps. Nothing is lost — those prospects stay on the list, and they're still reachable on any channel where you do have their details (their email address for a cold email step, their LinkedIn profile for a LinkedIn step).

So if you launch an Instagram campaign and fewer people are reached than you expected, the usual reason is that some prospects don't have an Instagram handle on file. Add the missing handles (re-import with the handle column mapped, or paste them in) and those people become reachable on Instagram.

Can one audience work across Instagram, email, and LinkedIn?

Yes. A single list of prospects can carry an email address, a LinkedIn profile, and an Instagram handle at the same time, so the same audience can power your cold email, LinkedIn, and Instagram outreach. Each channel uses the detail it needs: the email step uses the email address, the LinkedIn step uses the LinkedIn profile, and the Instagram step uses the Instagram handle.

When a channel doesn't have the detail it needs for a given person, it skips that person for that channel's steps — so a prospect with only an email address is emailed but passed over for Instagram, and a prospect with only an Instagram handle is messaged on Instagram but passed over for email. This is what lets one well-built audience run a coordinated multichannel sequence without any manual sorting. And if a prospect replies on any channel, WarmySender stops following up on the others for that person, so a multichannel effort stays coordinated and human.

Common questions about building an Instagram audience

Can I search Instagram for prospects inside the app?

No — there's no prospect-search box for Instagram in WarmySender. Instagram's platform doesn't allow prospect discovery through connected tools the way LinkedIn does, so instead you bring the handles you already have: upload a CSV with an Instagram Username / URL column, or paste @handles into the campaign wizard. Bringing your own hand-picked audience also keeps your account safer, because you're reaching people you genuinely chose rather than a scraped list.

What format should Instagram handles be in?

Any of these work, and you can mix them in the same list: a handle with the at-sign (@janedoe), a bare handle (janedoe), or a full profile link (instagram.com/janedoe or https://instagram.com/janedoe). WarmySender reads all of these as the same person, so you don't have to reformat your spreadsheet — just make sure each person's handle is in the column you map to Instagram Username / URL.

Can I mix Instagram and email or LinkedIn contacts in one list?

Yes. One list can hold people identified by email, by LinkedIn profile, by Instagram handle, or any combination. When you run that list as an Instagram campaign, everyone with an Instagram handle is reached on Instagram and everyone without one is skipped for the Instagram steps. The same list can also power an email or LinkedIn campaign, each using the detail it needs — which is exactly how a multichannel sequence reaches the same person across channels.

Why were some of my prospects skipped on Instagram?

Almost always because those prospects don't have an Instagram handle on file. Instagram steps can only reach a person who has a handle, so anyone without one is quietly passed over for the Instagram steps while the campaign continues for everyone who does. Add the missing handles — re-import your CSV with the handle column mapped to Instagram Username / URL, or paste the handles into the campaign — and those people become reachable on Instagram.

Do I have to save my audience as a list, or can I just paste handles?

Either works. If you want a reusable, named audience you can attach to more than one campaign, upload a CSV on the Prospects page and save it as a list (Method A). If you just want to launch quickly with a specific set of people, paste @handles — one per line — into the campaign wizard's Prospects step (Method B), and WarmySender builds the audience for that campaign on the spot. You can also start from a saved list and paste a few extra handles in the wizard.

Where exactly do I map the Instagram handle column when importing?

On the Prospects page, choose Import and select your CSV. WarmySender then shows a column-mapping screen. Match the column that holds your handles (for example instagram_username) to the Instagram Username / URL field, and map first_name and last_name to their fields. Any other columns can be mapped to custom fields for personalization. Then save everyone to a named list, and that list is ready to select in an Instagram campaign.

How many Instagram prospects should I add?

There's no fixed limit on your list size, but every account sends inside safe daily and hourly limits (a combined budget of 100 actions a day and 10 an hour), so a large list is worked through gradually rather than all at once — and a brand-new account starts slower while it ramps. A smaller list of well-chosen, genuinely relevant people almost always earns better replies than a huge generic one. See Instagram daily and hourly sending limits for how many people a sequence reaches per day.

Common adjacent questions about building an Instagram outreach list.

How do I import Instagram usernames into WarmySender?

Upload a CSV on the Prospects page with a column of Instagram handles, and on the mapping screen match that column to the Instagram Username / URL field, then save everyone to a list. The handles can be @handle, a bare handle, or an instagram.com/... link. Your saved list is then selectable as the audience in any Instagram campaign. For a quick one-off, you can instead paste handles straight into the campaign wizard.

Does WarmySender scrape Instagram to find leads?

No. WarmySender doesn't scrape Instagram or search it for prospects — you bring the handles you already have. That's a deliberate account-safety choice: reaching people you've genuinely chosen, at a safe, paced rhythm, is far safer for your account than acting on a scraped list. WarmySender then runs your outreach to exactly the handles you added, inside safe daily and hourly limits.

Can I add just one Instagram prospect?

Yes. You can paste a single @handle into the campaign wizard's Prospects step, or import a one-row CSV and save it to a list. Either way, the campaign reaches that one person on Instagram just as it would a larger audience — following, liking, and messaging them on a safe, paced schedule.

What if I only have Instagram handles and no names or emails?

That's fine — the only thing an Instagram campaign needs to reach someone is their handle. Names and emails just let you personalize DMs or run the same person on other channels; without them, your Instagram outreach still works. If you do add a first name, you can personalize with a variable like {{first_name | default: 'there'}} so a missing name still reads naturally.
