ExpandedToggleIcon        Connection Dialog

To connect to Mailchimp, you need to click the Web Login button and sign in to your Mailchimp account in the opened browser page.

Additionally you may configure Advanced connection options for more fine connection tuning.


ExpandedToggleIcon        Advanced Connection Options

The following table describes the options that you can include in the Connection String using the Advanced Connection Editor dialog box:





A key that grant access to your Mailchimp account. Filled automatically when you perform web login as described above.

API Version

Determines the Mailchimp API version to use to interact with Mailchimp. Note that different API versions provide access to somewhat different sets of objects and fields.

Connection Lifetime

When a connection is returned to the pool, its creation time is compared with the current time, and the connection is destroyed if that time span (in seconds) exceeds the value specified by Connection Lifetime. The default value is 0 (connection always returns to pool).

Connection Timeout

The length of time (in seconds) to wait for a connection to the server before terminating the attempt and generating an error. The default value is 15.

Default Command Timeout

The time in seconds to wait while trying to execute a command before terminating the attempt and generating an error.

Failover Retries

The number of retry attempts to automatically re-run a command before displaying an error message in case when the command failed because of an error that may be temporary.

Local SQL Engine

Determines whether to use local SQL engine for SELECT queries, that are too complex to translate them directly to Mailchimp API calls or to show an error message.

Max Pool Size

The maximum number of connections allowed in the pool. Setting the Max Pool Size value in the connection string can affect performance. The default value is 100.

Merge Fields Detection Behavior

Determines how to present Mailchimp merge tags when working with the ListMembers table. Merge tags are custom fields of the ListMembers table in Mailchimp. It's own set of merge tags can be added for list members of each list; however, Skyvia presents all tables, including Mailchimp ListMembers, so that all its rows have the same columns. Merge Fields Behavior parameter

The following values are available for this setting:

None - all merge tags are not read from Mailchimp and not added as ListMembers table fields.
JoinCommon - only merge tags that are defined for all the Lists are added as ListMembers table columns. Other tags are ignored. This is the default value.
JoinAll - all the merge tags are joined to other ListMembers table columns (except for the case described below). If a merge tag is not defined for the list, a list member belongs to, NULL value is returned for the corresponding column of this list member.

If different lists have merge tags with the same name but different type, default value, required setting, etc., these merge tags are ignored regardless of the Merge Fields Behavior parameter. Merge tags that have the same name for different lists must be the same in order to be available in Skyvia.


note Note

Reading merge tag information takes some time. If you don't to use merge tags, set this parameter to None for best performance.

Min Pool Size

The minimum number of connections allowed in the pool. The default value is 0.

Persist Security Info

Indicates if security-sensitive information, such as the password, is not returned as part of the connection if the connection is open or has ever been in an open state.


If true, by default, the connection is drawn from the appropriate pool or is created and added to the appropriate pool.

Proxy Host

The host name or IP address of proxy server.

Proxy Password

The password for the proxy server account.

Proxy Port

The port number of the proxy server. The default value is 3128.

Proxy User

The proxy server account name.


Indicates whether the connection is read-only (allows only SELECT statements).

Token Server

Not used for Mailchimp.

Use Merge Tag As Field Name

Determines whether to use merge tag values as custom field names or use label values instead.

UTC Dates

If set to True, dates will be converted to UTC format during import, and the date values entered in Excel are considered UTC dates when saving them to the data source.
