Alert vs Instantly: the reason and the send.
Instantly is built for the volume campaign: unlimited mailboxes, warmup, inbox rotation, and a 450 million contact lead finder that can build you a Shopify list from its technology filter. Alert is built for the precision campaign: the Shopify merchant who just gave your competitor a one-star review, one email, written to that review, sent to the founder. Teams that run both use Alert to pick the merchant and Instantly to deliver the email.

A cold-email engine
Volume sending done properly: unlimited email accounts, automated warmup, deliverability tooling, a shared reply inbox, and a lead finder with firmographic, technology and intent filters. Filter on Shopify and it will build you a Shopify list to fill the campaign.
The list, and the reason for it
Alert watches Shopify storefronts and the App Store for the moments a merchant is open to change, then hands you the merchant, the person and a draft that names what just happened. Short lists, one email each, high touch. It does not send anything.
Volume or precision
Instantly is great at the volume campaign: a Shopify-filtered list of thousands, sent from rotating inboxes. Alert is built for the precision campaign: forty merchants who each have a reason this week, one email each, written to the reason. If you already have the engine, Alert is the short list.
What each one actually does
Instantly figures are from its published plans. Alert's are the same ones on our pricing page.
| Instantly | Alert | |
|---|---|---|
| Built for | High-volume cold email at scale, with the infrastructure to land in the inbox. | Finding in-market Shopify merchants and the person to write to, with the reason already in hand. |
| Campaign style | Volume: thousands of sends per campaign, rotating inboxes, warmup, a shared reply box. | Precision: a short list, one email per merchant, written to what just happened, sent by a person. |
| List building | A 450M+ B2B lead finder with job title, company size, industry, intent and technology filters. Yes, you can build a Shopify-specific list from the technology filter, plus your own uploads. | Shopify merchants only, resolved from the storefront: stack, plan, vertical and a named contact, 800,000+ on file. The list is built from what happened this week, not from a filter. |
| Buying signals | Company-level intent and enrichment filters at list-build time. A Shopify filter tells you the platform, not what happened on the store. | Five store-level feeds, timed to the event: competitor reviews, installs and uninstalls, Plus upgrades, hiring, competitor ads. |
| Personalization | AI email writer, templates, variables and spintax. | The merchant's actual complaint, competitor and stack turned into the opening line. Every negative review scored and summarized. |
| Sending | Unlimited email accounts, warmup, rotation, deliverability network, Unibox replies. | Alert does not send email. Drafts hand off to your sequencer, including Instantly, or to Claude or ChatGPT. |
| Pricing | Outreach from $47 to $358 per month by volume; lead credits from $47 per month; bundles and agency plans above that. | $199 per month flat, unlimited seats, 14-day free trial, no credits. |
| Where it fits | The volume campaign, and the last mile of any campaign: the send, the warmup, the reply inbox. | The precision campaign: who is in market on Shopify today, why, and the one email that names it. |
A Shopify list is a platform list. A precision list is an event list.
Sending is a solved problem you can rent by the month. The list is the bottleneck. A Shopify-filtered list from a general database tells you the platform. It has no idea what happened on the store this week, and a precision campaign lives on exactly that.
Instantly's lead finder will build a list of companies running Shopify. It cannot tell you which of them run your competitor, that one dropped it on Thursday, upgraded to Plus, or hired a Head of Retention. Those are the emails that get replies.
A volume campaign wins on inbox placement and send count. A precision campaign wins on the reason and the timing, and dies on a template. Alert turns a five-thousand-row list into the forty merchants with a reason right now, each with a named contact.
Alert's drafts quote the merchant's own complaint and the competitor it was about. That is personalization a template cannot fake, and it is ready before the send window opens.
Rows: 5,000
Reason to write: none specific
Opening line: template with a first-name variable
Rows: 40, each with a named contact
Reason to write: the review, posted this week
Opening line: drafted from the complaint
Illustrative. Row counts vary by category and watchlist; the shape of the list is the point.
Which one you should pick
These two are not really rivals. One is for the volume campaign, the other for the precision campaign, and most teams run both.
Pick Instantly if
- You need sending infrastructure: many mailboxes, warmup, rotation and a shared reply inbox. Alert never replaces that.
- Your motion is the volume campaign: build a Shopify-filtered list of thousands inside the sending tool and optimize on deliverability and send count.
- You sell outside Shopify and need a general lead database with broad filters.
- You want the AI writer, templates and campaign analytics in the same tool as the send.
Pick Alert if
- You run precision campaigns: short lists, one email each, high touch, written to what just happened.
- You want the list built from store-level events, which app a store runs and what changed, not a platform filter over a static database.
- You want each email to name the merchant's actual complaint, competitor or upgrade.
- You already have a sender and what it lacks is a list worth sending to.

Instantly and Alert, answered.
Can I use Alert with Instantly?
Yes, that is the most common setup. Alert finds the merchants and drafts the message; Instantly sends it. Today the handoff is copy-and-paste or through Claude or ChatGPT, which can write the lead into Instantly if it is connected there. Alert has no native Instantly connector yet and we would rather say that plainly.
Does Alert warm up inboxes or manage deliverability?
No. Alert does not send email at all, so there is nothing to warm up. Keep your sending stack; Alert improves what goes into it.
Can Instantly build a Shopify list on its own?
Yes. Its lead finder has a technology filter, so you can build a list of companies running Shopify and send to it. That is a platform list, and it is the right input for a volume campaign. Alert's list is app-level and event-timed: which merchants run your competitor, and which of them gave it a reason to be replaced this week. That is the input for a precision campaign.
How many leads does Alert produce a week?
It depends on the category and how many competitor apps you watch. Negative reviews are the scarcest and strongest signal, typically a handful per app per month; installs and uninstalls, Plus upgrades and hiring are steadier. The point is that each one arrives with a reason and a person, not that the list is long.
