Alert vs Apollo, for Shopify app sales.
Apollo is a general-purpose B2B database and sequencer: hundreds of millions of contacts, a technology filter that can tell you a company runs Shopify, and the tools to email and call them. Alert only knows Shopify merchants, and knows them at the app level: which competitor app a store installed, which one it dropped, and who left the one-star review yesterday. One is a system of record for outbound. The other is the reason to reach out.

A database for any market
Contacts, companies, intent topics, a technology filter across 1,500+ technologies, plus sequences, a dialer and meeting booking. Priced per seat with credits for email and mobile reveals.
App-level intelligence on Shopify
Alert crawls the storefront, so it knows which of 4,000+ apps a store runs today and when that changed. Reviews, installs, Plus upgrades, hiring and ads become alerts with the merchant and a named contact attached.
Platform or app
Apollo can filter to companies that run Shopify. That is 1.5 million stores wide. Alert filters to the stores that run your competitor and gave it a reason to be replaced this week. That is the list a rep can actually work.
What each one actually does
Apollo figures are from its published plans and help center. Alert's are the same ones on our pricing page.
| Apollo | Alert | |
|---|---|---|
| Built for | Any B2B team prospecting any market, with sequencing and calling built in. | Teams selling apps and services to Shopify merchants, who need to know which merchants are in market now. |
| Technology depth | Technologies filter across 1,500+ technologies, including Shopify as a platform. Apollo describes it as sourced from web scans and third parties. | App-level detection from the storefront: which of 4,000+ Shopify apps a store runs today, resolved against a 21,000-app catalog, re-crawled on a rolling cadence. |
| Buying signals | Account-level intent topics, job changes, funding and headcount. | Store-level events: a one-star review on a competitor app, an uninstall, a Shopify Plus upgrade, a retention hire, a new ad campaign. Dated, per store. |
| Contacts | Hundreds of millions of B2B contacts. Email and mobile reveals draw down a credit balance. | 800,000+ Shopify merchant contacts, graded, attached to the signal. No credits, no reveal step. |
| Outreach | Sequences, dialer, meetings and deliverability tooling inside the product. | AI-drafted outreach per signal that names the merchant's actual complaint, handed to the sequencer you already use. Alert does not send email. |
| Pricing | Free tier. $49 to $119 per user per month billed annually, more month to month, plus credits. The Organization plan needs three seats. | $199 per month flat, unlimited seats, 14-day free trial, no credits. |
| Where it fits | Your system of record for sequencing and general prospecting. | The source of who to contact on Shopify, and why, today. |
A platform filter is not a buying signal
Knowing a company runs Shopify puts it in a category. Knowing which app it runs, and that the app just failed them, puts it on today's list.
Filter a general database to Shopify and you get the platform: every store, from a side project to a Plus brand. A technology filter reaches the platform and the biggest vendors. It is not built to reach the long tail of Shopify apps, or to tell you a store is unhappy with one.
Every merchant in Alert is resolved from the store outward: domain, stack, plan, vertical, then the person. That is why small brands with thin firmographic records still show up with a real contact.
A review that says the widget broke checkout, posted Tuesday, is worth more than a hundred filters. Alert scores it, summarizes the complaint, and writes the opening line so the email goes out Tuesday.

Which one you should pick
Most Shopify app teams end up with both. The question is which one drives the day.
Pick Apollo if
- You sell to companies that are not Shopify merchants, or across several markets at once.
- You need sequencing, a dialer and meeting booking in one tool and want to run outbound inside it.
- You need mobile numbers at scale and are comfortable buying them on credits.
- You want the largest possible general contact database and will build your own targeting on top.
Pick Alert if
- Your buyers are Shopify merchants and your competitors are Shopify apps.
- You want to know which app a store runs and when it changed, not just that it runs Shopify.
- You want the merchant's actual complaint, Plus upgrade or hire to be the reason for the email.
- You want one flat price for the whole team and no credit meter between you and a contact.

Apollo and Alert, answered.
Can I use Alert alongside Apollo?
Yes, and many teams do. Alert supplies the who and the why on Shopify: which merchant, which signal, which stack. Apollo, or any sequencer, handles the sending. Any Alert lead hands off in one click to Claude or ChatGPT, which can write it into the tools they are connected to.
Does Alert send email or run sequences?
No. Alert drafts the outreach from the signal and hands it to whatever you send from: Gmail, Outlook or your sequencer. Keeping sending out of the product is deliberate.
Does Alert have a technology filter like Apollo's?
Every store in Alert is a Shopify store, so the filters go one level deeper: which apps a store runs, whether it is on Shopify Plus, its vertical and country, and which signals it has fired recently. The Install Base view lists every store running any app on your watchlist.
Are Alert's contacts metered?
No. There are no credits, reveal fees or per-seat charges. One flat plan, unlimited seats, every contact and signal included from day one of the trial.
Run both. Compare the replies.
14 days free, then one plan at $199/mo. GTM should run on signals, not guesswork.
