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

> What Constant Contact's 300-integration claim amounts to: nine named, a directory behind HTTP 403, a monitored API component, and an official Shopify app scoring 2.9 from 25 reviews against Klaviyo's 4.7 from 3,362.

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.



> 💡 **undefined:** Read the official app's reviews on the platform's own store rather than the vendor's integration count. Twenty-five reviews of the real thing beat three hundred of anything.

## 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 [21]. 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.



> 💡 **undefined:** If several third-party connectors exist for the same pairing, the official one has gaps — and one of them may be the better buy.

## 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.



> 💡 **undefined:** Ask support what an integration syncs and in which direction. 'Import your data' is the vendor's own framing and it is one-directional.

## 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 [21]
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.



> ⚠ **undefined:** No list of the 300 exists for any reader outside a browser, and no API documentation, rate limit or changelog was readable.

## 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.



## FAQ

**How many integrations does Constant Contact have?**

The vendor claims 300 and names nine: Google, Microsoft, Facebook, Canva, LinkedIn, Vimeo, Zapier, Shopify and Eventbrite. The directory page behind the number returns HTTP 403 to every automated reader we tried, from two networks and with a browser user-agent, so the count cannot be checked against a list except by a person in a browser. Zapier being on the named list matters most, because it is itself a directory and covers the long tail without the vendor building anything.

**Does Constant Contact integrate well with Shopify?**

The vendor publishes an official app, Constant Contact: Email & SMS, and it scores 2.9 out of 5 from 25 reviews — the lowest figure this vendor carries on any property we could read. Klaviyo's listing on the same store scores 4.7 from 3,362 reviews. Several third-party apps exist whose only purpose is connecting Shopify to Constant Contact, and one of them outscores the official app. If commerce is your primary channel, read those reviews before committing.

**Does Constant Contact have an API?**

Yes, and we can prove that much without reading its documentation: API's and Integrations is one of 24 named components on the vendor's public status page, each with a live state, and exactly one of the fifty incidents published since June 2024 names it. A vendor does not monitor a component it does not run. What we could not read is the reference, the authentication model, the rate limits or a changelog, because the developer-facing pages sit behind the same 403 as the rest of the commercial site.

## 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.
