Microsoft AppSource Email Scraper

Microsoft AppSource Email Scraper — publisher contacts from the Microsoft business app marketplace

The Microsoft AppSource Email Scraper collects publicly indexed contact emails for software publishers listed on Microsoft AppSource and Azure Marketplace. It turns a handful of keywords into a clean, deduplicated dataset of publisher emails, account names and listing URLs. Everything it returns already sits in Google's public index — nothing is unlocked, logged into, or pulled from a private API.

AppSource is a B2B catalogue, not a consumer store. Publishers put support, sales and partnership addresses on their listings on purpose, because that is how Microsoft customers and resellers are supposed to reach them. That makes the Microsoft AppSource Email Scraper a natural fit for ISV partner sourcing, integration partnerships and channel research.

If you have ever tried to build a Microsoft partner email list by hand, you know the problem: thousands of offers, no export button, and contact details scattered across listing pages. The Microsoft AppSource Email Scraper automates the search side of that job so you can spend your time on the outreach instead. Run it from the Apify console, from the API, or on a schedule, and the Microsoft AppSource Email Scraper writes straight into an Apify dataset.

What the Microsoft AppSource Email Scraper actually does

The Microsoft AppSource Email Scraper is a Google SERP harvester with a hard domain filter. It builds site:appsource.microsoft.com and site:azuremarketplace.microsoft.com queries around your keywords, reads the result pages, and pulls email addresses out of the titles and snippets.

It does not log into Microsoft AppSource, use the AppSource or Azure Marketplace API, or open the marketplace website in a browser. There is no JavaScript rendering, no authentication and no cookies — only publicly indexed search results.

Who this Microsoft AppSource email extractor is built for

Partner managers use the Microsoft AppSource Email Scraper to build an ISV recruitment pipeline for a Microsoft 365, Dynamics 365 or Azure ecosystem play. Integration teams use it to find AppSource publisher contacts before proposing a technical partnership.

Agencies and consultancies source business app vendors for client implementations. Analysts point the Microsoft AppSource Email Scraper at a category to run competitive and market research across the Microsoft business app marketplace.

Teams chasing the wider Microsoft developer ecosystem often pair it with the GitHub Email Scraper for open-source maintainers, or the Zapier App Directory Email Scraper for automation vendors who integrate with the same stack.

Key features of the Microsoft AppSource Email Scraper

Everything below is behaviour the Microsoft AppSource Email Scraper actually implements — no roadmap items, no marketing filler.

Feature	What it means in practice
Google site: targeting	Every query is scoped to appsource.microsoft.com and azuremarketplace.microsoft.com, so results stay inside the Microsoft marketplace
Query expansion	Each keyword × domain pair is searched as a base query, a quoted query, an intitle: query, and one variant per query modifier
Domain-filtered extraction	Only emails ending in the domains you list are kept, so you control the shape of the output
Global deduplication	Every email is unique across the whole run, no matter how many queries surfaced it
Obfuscation handling	Understands name [at] domain [dot] com, name (at) domain, name @ domain.com, domain .com, zero-width characters and the full-width ＠
Junk filter	Rejects placeholders such as email@, yourname@, test@, xxx@ and single-character locals
Boundary-correct matching	@gmail.com will not match inside @gmail.company or @gmail.com.br
Soft-wrap repair	Drops a hit that is only the tail end of another email in the same result block
Structural parsing	Locates the <h3> title and the smallest surrounding block instead of relying on Google's CSS class names
Whole-page fallback	If Google's markup changes, the run degrades to "emails without account details" rather than "no emails"
Block detection	CAPTCHA, "unusual traffic" and consent pages are detected and retried, not counted as empty
Retries and backoff	Up to 3 attempts per page with exponential backoff and a fresh proxy session per request
Requeue pass	Blocked or failed queries are re-queued once at the end of the run
Resumable state	Progress is stored in the key-value store, keyed by a hash of the input, and saved on PERSIST_STATE, MIGRATING and ABORTING
Concurrency control	An asyncio worker pool with a shared stop signal on maxEmails
Run summary	Logs pages fetched, blocked pages, retries and emails per page

How the Microsoft AppSource Email Scraper works

The pipeline is short and deliberately transparent.

1. The Microsoft AppSource Email Scraper reads your input: keywords, location, email domains and limits.
2. It builds Google queries with the site: operator against the AppSource and Azure Marketplace domains, for example site:appsource.microsoft.com microsoft partner "@gmail.com".
3. It fetches Google result pages through the Apify GOOGLE_SERP proxy using async aiohttp.
4. It parses each result block structurally, finding the <h3> title and the smallest block around it.
5. It extracts emails from the block text with a domain-filtered regex.
6. It deduplicates globally and pushes each lead to the Apify dataset immediately.

Because results are pushed as they are found, you can watch the dataset fill up while the Microsoft AppSource Email Scraper is still working. If the run is migrated or aborted, resumable state means the next start does not begin from zero.

Why query expansion matters on a marketplace domain

Google caps any single query at roughly 300 results. A marketplace like AppSource has far more listings than that, so one query can never see the whole catalogue.

Query expansion is how the Microsoft AppSource Email Scraper works around the cap. It rewrites each keyword into several phrasings and combines it with each query modifier, so many small queries collectively reach further than one broad query ever could.

Input settings for the Microsoft AppSource Email Scraper

Nine fields control the whole run. Only keywords is required; the Microsoft AppSource Email Scraper ships with sensible defaults for everything else.

Field	Type	Default	Meaning
keywords	array (required)	["microsoft partner", "business app"]	Search terms describing the publishers you want (niche, job title, industry)
location	string	""	Optional location phrase added to every query
customDomains	array	["@gmail.com","@yahoo.com"]	Only emails on these domains are kept; the leading @ is optional
maxEmails	integer 1–10000	20	Stop once this many unique emails have been collected
countryCode	string	""	Two-letter country code for the search proxy (US, GB, DE...)
expandQueries	boolean	true	Search each keyword × domain pair in several phrasings
queryModifiers	array	["email","contact","support","developer","publisher"]	Extra words combined with each keyword when expansion is on
maxPagesPerQuery	integer 1–50	30	Page cap per query
maxConcurrency	integer 1–20	5	How many queries run in parallel

Example input for a Microsoft partner email list

{
  "keywords": ["microsoft partner", "dynamics 365 app", "power platform isv"],
  "location": "United Kingdom",
  "customDomains": ["@gmail.com", "@outlook.com"],
  "maxEmails": 400,
  "countryCode": "GB",
  "expandQueries": true,
  "queryModifiers": ["email", "contact", "support", "developer", "publisher"],
  "maxPagesPerQuery": 30,
  "maxConcurrency": 5
}

Start narrow. Two or three precise keywords with a low maxEmails will tell you very quickly whether a niche is well indexed before you commit to a large run.

Output fields from the Microsoft AppSource Email Scraper

Every dataset item the Microsoft AppSource Email Scraper produces carries all fourteen fields below. There are no optional or conditional keys — only conditional values.

Field	Meaning
network	Platform name
keyword	The keyword that produced the lead
query	The exact Google query used
title	Raw result title
accountName	Account label Google prints
fullName	Display name parsed from a profile-style title; empty for non-profile results
username	URL-safe handle when the platform exposes one; otherwise null
profileUrl	Canonical listing URL when a handle is known; otherwise empty
url	Direct platform link when exposed, else the profile URL
description	Bio or snippet text, cleaned of labels and counters
email	Lower-cased email address
emailDomain	The matched domain (e.g. @gmail.com)
possiblyTruncated	true when Google's snippet ellipsis touched the email — verify before sending
foundAt	ISO 8601 UTC timestamp

Example output row

{
  "network": "Microsoft AppSource",
  "keyword": "dynamics 365 app",
  "query": "site:appsource.microsoft.com dynamics 365 app contact \"@gmail.com\"",
  "title": "Northwind Field Service - Microsoft AppSource",
  "accountName": "Northwind Solutions",
  "fullName": "Northwind Solutions",
  "username": "northwindsolutions.field-service",
  "profileUrl": "https://appsource.microsoft.com/en-us/product/northwindsolutions.field-service",
  "url": "https://appsource.microsoft.com/en-us/product/northwindsolutions.field-service",
  "description": "Field service scheduling for Dynamics 365. Partnership enquiries: partners.northwind@gmail.com",
  "email": "partners.northwind@gmail.com",
  "emailDomain": "@gmail.com",
  "possiblyTruncated": false,
  "foundAt": "2025-04-18T09:41:07Z"
}

Results from the Microsoft AppSource Email Scraper land in an Apify dataset, so you can export to CSV, JSON, Excel or XML, or pull them through the Apify API into your CRM.

Use cases for the Microsoft AppSource Email Scraper

Because AppSource is a B2B catalogue, the Microsoft AppSource Email Scraper is aimed at partnership and vendor work rather than consumer prospecting.

Use case	How the Microsoft AppSource Email Scraper helps
ISV partner recruitment	Build a shortlist of AppSource publisher contacts in a product category you want to co-sell into
Integration partnerships	Find business app publishers whose offers complement yours and reach the person who handles partnerships
Agency and vendor sourcing	Assemble a Microsoft partner email list for an implementation project or an RFP shortlist
Competitive research	Map which vendors publish in a category and how they present themselves on the marketplace
Channel and reseller programmes	Identify Azure Marketplace publishers who might join a reseller or co-sell motion
Market sizing	Sample listings by keyword to understand how crowded a Microsoft business app niche really is
Event and community outreach	Source speakers, sponsors or panellists from a specific AppSource segment
Data enrichment	Match scraped publisher contacts against an existing account list to fill contact gaps

Practical example: sourcing Dynamics 365 ISVs

Set keywords to ["dynamics 365 app", "dynamics 365 isv", "business central app"]. Keep expandQueries on so each keyword is combined with email, contact, support, developer and publisher.

Add @gmail.com and @outlook.com to customDomains if you want independent publishers rather than large corporates. Raise maxEmails gradually once the first small Microsoft AppSource Email Scraper run shows the niche is productive.

Tips for getting more from the Microsoft AppSource Email Scraper

Keep keywords specific to a product category rather than generic. "power bi visual" will out-perform "software" every time on a Microsoft AppSource email extractor run.

Use customDomains as a segmentation control, not just a filter. Free-mail domains skew towards independent publishers; corporate domains skew towards established vendors.

Set countryCode when you need a regional slice of the Microsoft partner ecosystem. Combine it with location for a tighter geographic focus.

Leave maxConcurrency near the default unless you have a reason to change it. Higher concurrency does not make the Microsoft AppSource Email Scraper find more indexed emails; it only spends your proxy budget faster.

Run the Microsoft AppSource Email Scraper on a schedule with the same input. Google's index changes, so a monthly run keeps a Microsoft partner email list fresh without redoing the research.

Widen coverage sideways rather than deeper. Running the Docker Hub Email Scraper or the Slack App Directory Email Scraper with the same keywords often surfaces the same vendors under a different public identity.

Limitations of the Microsoft AppSource Email Scraper

These are real and you should plan around them.

• Publicly indexed emails only. If a publisher's address is not visible in Google's index, the Microsoft AppSource Email Scraper cannot find it. Contact forms and images are invisible to it.
• Google's ~300-result cap. A single query returns roughly 300 results at most. Query expansion exists precisely because of this ceiling.
• possiblyTruncated. When Google's snippet ellipsis touches an email, the field is set to true. Verify those rows before sending anything.
• username and profileUrl are conditional. They are only populated when Google's result exposes a handle. Some rows will have accountName and fullName but an empty username and profileUrl. That is a Google limitation, not a bug.
• Apify GOOGLE_SERP proxy required. The Microsoft AppSource Email Scraper cannot run without Apify proxy credentials.
• Free-plan cap. Free Apify plans are capped at 100 emails per run; paid plans are uncapped.
• No guaranteed volume. Results vary with keywords, domains and location, and no volume is guaranteed.

In our own measured testing, a small Microsoft AppSource Email Scraper run returned 7 usable rows out of 7 targeted results — a strong hit rate for a B2B marketplace, but not a promise about your keywords.

FAQ about the Microsoft AppSource Email Scraper

Does the Microsoft AppSource Email Scraper use the Microsoft AppSource API?

No. It does not use any Microsoft API, does not log in, and does not open the marketplace website. All data comes from publicly indexed Google search results.

Is this Actor affiliated with or endorsed by Microsoft?

No. It is an independent tool that reads public Google search results. It is not officially supported by, affiliated with or endorsed by Microsoft.

Why does the Microsoft AppSource Email Scraper leave username and profileUrl empty on some rows?

Those fields are only filled when Google's result exposes a usable handle. When Google shows only a display name, you still get accountName and fullName, but no handle. This is a Google limitation, not a bug.

What does possiblyTruncated: true mean?

Google cut the snippet with an ellipsis right where the email sits, so the address may be incomplete. Treat those rows as leads to verify rather than addresses to mail.

How many emails can one Microsoft AppSource Email Scraper run return?

Free Apify plans stop at 100 emails per run. Paid plans are uncapped and bounded by your maxEmails value, which ranges from 1 to 10000.

Do I need a proxy?

Yes. The Microsoft AppSource Email Scraper requires the Apify GOOGLE_SERP proxy and cannot run without Apify proxy credentials.

Why did I get fewer emails than maxEmails?

Google caps a single query at roughly 300 results, and only some listings expose an email in the index. Broadening keywords and customDomains usually helps the Microsoft AppSource Email Scraper more than raising maxPagesPerQuery.

Should I turn expandQueries off?

Usually not. Expansion is the main defence against Google's per-query result cap. Turn it off only when you want a fast, narrow probe of a single phrasing.

Does the Microsoft AppSource Email Scraper cover Azure Marketplace as well as AppSource?

Yes. Queries are scoped to both appsource.microsoft.com and azuremarketplace.microsoft.com, so both catalogues are in scope.

Can I restrict results to a country?

Set countryCode to a two-letter code for the search proxy, and optionally add a location phrase that the Microsoft AppSource Email Scraper appends to every query.

Can I resume an interrupted run?

Yes. The Microsoft AppSource Email Scraper stores progress in the key-value store keyed by a hash of your input, and saves on Apify's PERSIST_STATE, MIGRATING and ABORTING events.

Is the data compliant to use?

The Actor only collects addresses that are already public in Google's index. You are responsible for how you use them, including GDPR, CAN-SPAM and any other applicable rules in your market.
