# FAQs

> Common questions, expected behaviors, and troubleshooting for the Constant Contact Email data source.

## Why don't my Constant Contact Email metrics change when I adjust the date range?

Constant Contact's stats API returns **lifetime totals per campaign** rather than a day-by-day time series, so the metric values in a report are cumulative counts for each campaign's entire life.

Because of this, the date range in Adriel controls **which campaigns appear** in a report — not the numbers inside them. A campaign is included when its **campaign created-at** or **campaign updated-at** timestamp falls within the selected range. Widening or narrowing the range adds or removes whole campaigns, but it does not slice a campaign's totals down to a specific period.

To compare activity across periods, group by the campaign created-at or campaign updated-at breakdown rather than expecting the totals themselves to change. For the full list of metrics and breakdowns, see the [Constant Contact Email data reference](/data-sources/a-f/constant-contact-email/data-reference).

## Why did my Constant Contact Email data source disconnect and ask me to reconnect?

Constant Contact authorizes the connection with a refresh token, and Adriel renews access automatically in the background. Constant Contact can invalidate or expire that refresh token on its side — for example after a password change or a long period of inactivity.

When the token is no longer valid, Constant Contact returns `The refresh token is invalid or expired.`, and Adriel disconnects the data source so the problem is visible rather than silently returning stale data. Reauthorizing restores the connection; follow [How to connect Constant Contact Email to Adriel](/data-sources/a-f/constant-contact-email/how-to-connect) again to sign back in.

If the data source keeps disconnecting immediately after each successful reconnect, email `support@adriel.com` with the account details so the connection can be investigated.

## Why is the older combined "Constant Contact" connector no longer available?

Constant Contact's platform is now split into two separate connectors in Adriel — **Constant Contact Email** and **Constant Contact SMS** — that share the same OAuth account but expose different metrics and behave differently. The older general-purpose connector that combined email and SMS is deprecated and can no longer be created.

Email campaign performance comes through Constant Contact Email. For text-message campaign metrics on the same account, add the sibling data source and see the [Constant Contact SMS data reference](/data-sources/a-f/constant-contact-sms/data-reference).

## Why is the first sync slow for an account with many campaigns?

On first connection, the connector imports the account's full email campaign catalog along with each campaign's stats. Stats are requested from Constant Contact in **chunks of 40 campaign IDs per request** — a deliberate limit that keeps request URLs short enough to avoid Constant Contact's URL-length failures.

As a result, an account with a large number of campaigns makes proportionally more API calls, so its initial sync takes longer. Once the catalog is cached, later refreshes only need to reconcile changes.

## Why did a campaign disappear from my Constant Contact Email reports?

Each refresh reflects the campaign catalog that currently exists in Constant Contact. When a campaign is deleted on the Constant Contact side, it stops appearing in subsequent refreshes and is not retained in Adriel.

This is expected behavior: the connector mirrors the live catalog rather than keeping a separate archive of campaigns that no longer exist in Constant Contact.
