How to Scrape Emails from Instagram Post Likers (Competitor Promo Targeting)

If you're doing lead generation in a competitive space, broad targeting is often a budget burner and generates cold leads. A more efficient way is to target people that have already shown intent: users who liked a post of your competitor (sale, giveaway, launch, webinar, etc.). These users are often an "intent spike" because they just happened to interact with an offer in your category.

This guide walks you through an engagement-based targeting workflow: Extract likers from a competitor promo post, find publicly available emails from profiles/websites, clean the data, segment by intent, and run compliant outreach.

Important: This article is on collecting and using the public contact information only and encourages responsible outreach. Always ensure you are looking at the laws and regulations that apply to the area and application you are in.

What "scraping emails from post likers" really means

Many people think that it is possible to "pull emails directly from Instagram." It looks like this in real life: a sustainable workflow.

Get list of accounts who liked a post (usernames/profile links)

For each account, locate a public email if they have them on their bio, contact button, or on a website with which they are associated.

Export everything to CSV so that you can create a list of leads and segment.

Key point: Not all people have a public email so set expectations right AND always clean/validate your list to ensure deliverability.

Why competitor promo post likers are "warm" leads

A promo post (discount, giveaway, launch, waitlist, webinar) will take action. People who like these posts are usually in one of these groups:

• They have real interest and are busy with comparing options.
• They take up deals in your category.
• They may already be the customer of competitor - often high potential if you have a clear USP.

Compared to targeting based on followers, likers are typically "hotter" because the engagement has been more recent and more motivated.

Step 0: Select the right competitor promo post (don't get any junk leads)

Before you do anything else with the post, score it. This means that you will not be able to target viral memes or giveaways with low-quality people that are seeking out freebies.

Promo Post Scorecard (0-10)

Criteria	Rapid method to assess
Offer clarity	Is there a clear discount/bonus/launch/waitlist?
ICP fit	Are the people in your audience your ideal customer?
Geo/language match	Do they live in areas that you sell to?
Engagement quality	Are comments about pricing, shipping, how to buy?
Giveaway quality	Is the giveaway "light" or spammy (tag 10 friends, etc.)?
Freshness	Newer posts usually convert better
Volume	Sufficient likes to justify the effort (depends on niche)

Red flags to avoid

• Trend/meme posts (High like, low buying intention).
• Giveaways with mass tagging/follow chains (freebies galore).
• Geographical Mismatch of Audience

End-to-end workflow: Post URL - Likers - Public emails - Clean - Segment - Outreach

Step 1: Document the Source (to be able to track the performance)

To measure results by post, create a source tag:

competitor<brand>promo_<yyyymmdd>

Also capture - post URL, offer type, language/geo, any ICP notes.

Step 2: Export the likers list

Use Scravio's Post Likers workflow to extract like and export as a CSV file.

For this use case: Post Likers Email Extractor

Minimum fields to be retained: username, profile url, source tag, pull date.

Step 3: Enrich profiles in order to find public emails

Once you have usernames, enhance them in order to gather:

• Public email (if available)
• Website link
• Bio text (useful in keyword filtering)
• Business signals (as per case)

Use: Instagram Email Scraper

The desire is to transform "usernames" to "leads with contact info + context."

Step 4: Clean Validation (Don't Skip This)

This is what makes you have a sustainable outreach:

• De-duplicate email and user name (don't double send)
• Normalize fields (lowercase emails, trim whitespaces, column standardization).
• Validate basics (get rid of invalid syntax; reduce bounce risk).
• Maintain a suppression list (unsubscribed, complaints, hard bounces).

Step 5: Segment by intent (engagement based targeting)

Don't give the same message to everybody. Segment by signals:

Segment	Criteria	Best message angle	CTA
S1: Likers + commenters	Liked and commented (high intent)	"Better alternative" / "Bonus stack"	Demo/Trial
S2: Business profiles	Has website/business email	"We'll lessen switch cost" (setup/migration)	Audit/Call
S3: Keyword match	Bio contains pain point keywords	Lead magnet (resource)	Download/Opt-in
S4: Freebie patterns	Giveaway - signals only	Low volume, soft offer	Opt-in

Expected yield: How many emails are you going to get from 1,000 likers?

There is not fixed number - it depends on niche and user behavior. Instead, estimate with:

Estimated emails = Likers × Profile coverage rate × Validation pass rate

• Profile coverage rate: % that have public email (bio/contact/website).
• Validation pass rate: Percentage of emails that pass basic checks.

Practical tip: sample 200-500 accounts first to get a feel for how many of your niche's posts have been covered before scaling up to multiple posts.

Competitor promo targeting playbook: 5 angles to use

1. Better alternative: underlining your USP without basing it on the competitor.
2. Bonus stack: match the offer + add great bonuses (templates, onboarding, audit).
3. Lead Magnet Opt-in: Give Value First (More Compliance Friendly).
4. Switch cost reducer: Remove friction (free setup, migration help).
5. Social proof mirror: use case study - same industry/geo.

Recommended outreach process (4 emails)

• Email 1: relevance + quick value.
• Email 2: proof (case study, points of comparison, results)
• Email 3: offer + clear CTA.
• Email 4: breakup + reminder of how to opt out.

Even light personalization based on segment (bio keyword, website type, category) will be better than generic blasts.

Scale without harming the deliverability

• Keep lists separated by source tag (don't mix it all up).
• Increase in volume of ramps over time and watch for bounce/complaints.
• Focus on of higher quality segments (S1/S2) first; use of low volume or lead magnet only with riskier segments (S4).

Compliance and Responsible Usage

• Only gather and use information that is publicly available for contact.
• Avoid spam - send relevant messages, limit the frequency of messages, be transparent.
• Provide an obvious opt-out and respect it in a timely manner.
• Check rules that apply to your area (GDPR/ anti spam laws etc.). If necessary seek legal advice.

Conclusion: Engagement Based Targeting as a Starting Point to Get Warmer Leads

Competitor promo post likers are worth trying because they recently interacted with an offer in your category. If you have a structured workflow (pick the right post - export likers - find public emails - clean - segment - outreach), you'll have a warmer list that you can measure and improve over time.
