Constant Contact Integrations: Nine Named, Three Hundred Claimed, and the Official Shopify App Rated 2.9

Constant Contact claims "300 integrations" and names nine of them. That ratio is the honest starting point for this article, and it is not a complaint. It is the normal state of this category. What is unusual here is that the directory behind the number is not a page we could read, so the count cannot be checked against a list by anyone who is not sitting in a browser.

So we did what can be done: counted what is named, read what is readable, and measured the one integration surface that publishes its own evidence.

What the vendor actually names

The claim appears identically on all three tiers: "Import your data using 300 integrations, including Google, Microsoft, Facebook, Canva, LinkedIn, Vimeo, Zapier, Shopify, Eventbrite and more!" ^[2], with "300+ integrations" repeated in the feature table below it.

Those nine are worth reading as a set, because they describe the product's view of itself. Google and Microsoft are contact and calendar sources. Facebook and LinkedIn are the social channels it posts to natively. Canva is a design tool for the email editor. Vimeo is video embedding. Shopify is commerce. Eventbrite is events, which is interesting, given that the product has its own events capability on every tier.

And Zapier is the one that matters most, because it is the only entry on the list that is itself a directory. A Zapier connection means the long tail is reachable without the vendor building anything, and for most small operations that covers the gap between nine named and three hundred claimed.

What the named set does not include is any CRM, any accounting package, any helpdesk or any analytics platform. Those may well exist among the other 291; none of them is named where a buyer can see it.

## The one integration that publishes its own score

Here is the finding, and it is the opposite of what we expected.

Constant Contact's own Shopify app, "Constant Contact: Email & SMS", developer Constant Contact, carries a rating of 2.9 from 25 reviews . That is the lowest score this vendor holds on any property we could read, below its WordPress plugin at 2.6 only because the WordPress plugin is lower still, and far below its Trustpilot 4.0 and its Google Play 4.67.

Compare the same property for the category's depth leader. Klaviyo's Shopify listing scores 4.7 from 3,362 reviews, a hundred and thirty times the review volume at nearly two points higher.

When we measured Klaviyo we found a clean pattern: its score fell as the integration became less native, 4.7 on Shopify, 3.22 on BigCommerce, 2.8 on WordPress, 1.6 on Trustpilot. Constant Contact inverts it. The commerce platform where this category's ratings are usually highest is where this vendor's are lowest, and the general-audience properties are where it does best. That is a coherent picture rather than a contradiction: this is a product whose users are small businesses doing broad marketing, not merchants running commerce programmes.

A 25-review sample is small, and its value is positional rather than statistical. But the position is the point.

What third parties built to fill the gap

The clearest evidence about an integration is whether somebody else felt the need to build one.

Alongside the vendor's own Shopify app sit at least three third-party apps whose entire purpose is connecting Shopify to Constant Contact, one synchronising newsletter subscribers into a chosen Constant Contact list, another offering workflow automation between store and account from $9 a month, and a popup builder specifically for Constant Contact subscription forms. One of them scores 4.3 from 30 reviews, which is better than the official app.

Two readings of that, and both are probably true. The ecosystem is healthy enough that gaps get filled by people who want to fill them, which is a genuine asset. And the gaps exist, which is why a merchant's first question should be what the official integration actually does rather than whether one exists.

The same shape appears on WordPress. The vendor publishes its own plugin, Constant Contact Forms, which scores 2.6 from 107 ratings ^[12]. That plugin does one thing, forms, which is worth knowing before reading the score as a verdict on the platform. A narrow surface attracts narrow complaints.

If your stack depends on a specific platform, the actionable step is to read the official app's own reviews on that platform's store rather than the vendor's integration count. Twenty-five reviews of the real thing tell you more than three hundred of anything.

## The API exists, and we can prove that much

The vendor's integration claim is unverifiable, but the existence of a developer surface is not, because the status page names it.

"API's and Integrations" is one of 24 named components on the public status page ^[19], each with its own live state. A vendor does not monitor a component it does not run. In the fifty incidents published since June 2024, exactly one names the API, and it is labelled major ^[19], so the surface exists, it is watched, and it has failed publicly once in twenty-eight months.

That is a thinner statement than we could make about Klaviyo, where we read individual integration pages, a documented public API and an MCP server. Here we can confirm that an API is operated and monitored, and we could not read its documentation, because the developer-facing pages were not among the ones we got through to.

This is the reason the integrations axis scores 3.3 on our rubric rather than higher. The axis measures what a buyer can establish before paying, and nine named integrations plus a monitored API component is what is establishable. The vendor's three hundred may all be real; none of them counts toward a score a reader can check.

What the integrations actually have to do here

Worth stepping back, because the integration question matters differently for this product than for its rivals.

A deep ecommerce platform needs integrations to pull behaviour in: browse events, cart contents, order values, product catalogues. That is why Klaviyo's integration surface is load-bearing and why it publishes individual pages per commerce platform.

Constant Contact's job is different. One subscription already covers email, social posting and scheduling, a social ads manager, Google Ads Manager and SEO recommendations at Premium, and events with registration and payments on every tier ^[2]. The things a small operation would otherwise integrate are mostly inside the product.

So the integration list has two real jobs rather than one large one: getting contacts in, which is what the vendor's own phrasing emphasises, "Import your data using 300 integrations" ^[2], and pushing signup events in from wherever people actually sign up. Google, Microsoft, Facebook, Shopify and Eventbrite cover the first. Forms, the plugin and Zapier cover the second.

Measured against that job rather than against a commerce programme, nine named integrations is less of a gap than the count suggests.

## Events and Eventbrite, which is the odd one out

One name on the list deserves its own paragraph, because it says something about how the product is used.

Eventbrite is named as an integration ^[2] while the product itself carries "Host events, sell products, and take payments" on all three tiers ^[2], with Event Campaigns as a named status component ^[19]. The vendor both competes with Eventbrite and connects to it.

That is not a contradiction; it is a statement about customers. Organisations that already run ticketing somewhere else still want their registrants in their mailing list, and organisations starting fresh can skip the second vendor entirely. Both are real, and the integration exists for the first group.

For a buyer, the practical consequence is a question worth asking before migrating anything: if you currently pay a ticketing platform, is it doing something the built-in events capability cannot, or is it doing the same thing for a per-ticket fee? We cannot answer that from published pages, because the events feature page was not one we could read. But it is the comparison that most often changes the total.

An integration can move your price, which nothing on the integration page says

This is the connection nobody makes, and it is the most expensive thing in this article.

The vendor's own framing of its integrations is about getting people in: "Import your data using 300 integrations" ^[2]. Google, Microsoft, Facebook, Shopify and Eventbrite are all, in practice, contact sources.

Now read the billing rule beside it. Your price is a function of your contact band, and the band is set by the maximum: "Your pricing is based on the highest tiered number of active contacts you've had (0-500, 2501-5000, etc.), so if you go into a higher tier in your current month, your monthly subscription will reflect that going forward" ^[3].

So an integration that syncs contacts is a mechanism that can raise your subscription permanently, by the published rule, without anyone deciding to upgrade. Connect a Shopify store with four thousand historical customers to a four-hundred-contact account and the band moves. Sync a Google contact list, an Eventbrite attendee history, a Microsoft directory. Same mechanism.

None of this is hidden; it is simply documented in two different places that do not reference each other, which is this product's recurring shape.

The practical defences are straightforward. Before connecting any contact-source integration, know which band you are in and where the next boundary sits. Check whether the integration syncs everything or only new records, and ask support if the page does not say. And prefer connecting signup paths, forms, landing pages, event registrations, over bulk historical syncs, because those add contacts at the rate you can mail them rather than all at once.

## What the integration list is missing for a small business

Four categories are absent from the named nine, and each has a different workaround worth knowing.

No accounting or invoicing. For an operation that wants purchase history against a contact, the built-in route is the events and payments capability on every tier ^[2], which holds transactional facts natively rather than importing them.

No CRM. The vendor's answer here is a separate product, Lead Gen & CRM, with its own documentation, accounts as a first-class object and a Salesforce integration ^[20], and it is not included in Lite, Standard or Premium, nor priced on any page we could read.

No helpdesk or support-ticket platform. Klaviyo sells one as a separate meter; this product has no equivalent and names no integration for one. Where a rival would route a shopper conversation into the customer record, here the route is the phone line that comes with every tier ^[2].

No analytics platform beyond the built-in reporting, which the vendor itself warns does not match the billing view: "Resends are not included in the stats on the Reporting tab, so you should always refer to your account page to see your most accurate send count for the billing period" ^[4].

For each of those, Zapier is the generic answer and it is on the named list ^[2]. The honest caveat is that a Zapier path is a monthly cost somewhere else plus maintenance, which belongs in the comparison rather than in the integration count.

How to verify an integration before you buy

Five steps, all free, in the order that resolves fastest.

Search the platform's own app store or plugin directory for the official Constant Contact app, and read its reviews rather than its description. The Shopify listing at 2.9 from 25 reviews and the WordPress plugin at 2.6 from 107 ^[12] are both more informative than any claim.

Check whether third-party connectors exist for the same pairing. If several do, the official one has gaps — and one of those connectors may be the better buy.

Ask support to confirm the specific integration by name, and ask what it syncs in which direction. "Import your data" ^[2] is the vendor's own framing and it is one-directional; a merchant usually needs events flowing the other way too.

Check Zapier for the pairing as a fallback. It is on the named list ^[2], and a Zapier path with a monthly cost is still an answer.

And take the included 1:1 onboarding session ^[2] with your integration question written down. It is on every tier, the person on the call can check the directory you cannot, and it is the cheapest research available on this product.

## What we could not establish

Said plainly, because the gaps are part of the answer.

No list of the 300. The vendor's commercial site rate-limits automated readers: nine of its pages returned nothing on a four-path pass, four of them came through later in a single window, three different URLs served the same cookie-consent dialogue byte for byte, and a later pass was blocked on all nine. For any reader that is not a browser, the vendor's integration catalogue does not exist.

No API documentation. We can confirm an "API's and Integrations" component is monitored ^[19] and that one major incident has touched it; we could not read a reference, an authentication model, a rate limit or a changelog.

No webhook or event-model detail, no data-residency statement, and nothing about whether integrations differ by tier — the feature table repeats the same integration line on Lite, Standard and Premium ^[2], which suggests they do not, but suggestion is not publication.

What we can say is narrower and firmer: nine integrations are named by the vendor, one of them is a directory in its own right, an API is operated and monitored, the official commerce app is rated 2.9 by 25 merchants, and the official WordPress plugin is rated 2.6 by 107 site owners. Every one of those is checkable by a reader in a browser, which is more than the number 300 offers.

## The short version

Nine integrations are named, three hundred are claimed, and the difference is not checkable because the directory refuses automated readers. Zapier is on the named list, which makes the long tail reachable in practice.

The official Shopify app scores 2.9 from 25 reviews — the lowest figure this vendor carries anywhere, against Klaviyo's 4.7 from 3,362 on the same store. That inverts the ratings-by-nativeness pattern we measured at Klaviyo and tells you who this product is for: small businesses doing broad marketing rather than merchants running commerce programmes.

Third-party connectors exist for the same pairings and one of them outscores the official app, which is simultaneously evidence of a healthy ecosystem and of real gaps.

An API is operated and monitored, with one major incident in twenty-eight months of published history. Its documentation was not among the pages we could read.

And measured against what this product is actually for — getting contacts in and signup events flowing — nine named integrations is a smaller gap than the arithmetic suggests. The axis scores 3.3 because a buyer can verify nine, not because three hundred are untrue.
