Update tracking settings

Whether to embed the open-tracking pixel.

Whether to rewrite links through the click-tracking redirect.

Opt-in aggressive bot detection (strict user-agent patterns, datacenter and Microsoft Azure IPs, fast campaign and sequence clicks from IPs clicking other recipients' emails, cross-send IP sweeps). Off by default; enabling it can lower reported open and click rates.

Whether to track unsubscribe link clicks. When false, Sequenzy unsubscribe links go directly to https://sequenzy.com, even with a custom tracking domain. Actual unsubscribes and their email attribution are still recorded.

Whether to keep each sent email's rendered content and subject, and the IP address, user agent and country of opens and clicks. When false, sent-email records keep no body once the email is sent and store the email's name (campaign, template or sequence) in place of its subject, opens and clicks store no IP address, user agent or country, and view-in-browser links stop working. Body and subject rules apply to emails sent afterwards; IP address, user agent and country follow the setting at each open or click.

Default revenue attribution window in hours.

Whether new contacts must confirm by email before they become subscribed. This is the account-wide default that the per-request optInMode on subscriber creation overrides. Enabling it requires a sender profile and provisions the confirmation email automatically; it does not change contacts that are already active.

Where the hosted confirmation page sends subscribers after they confirm. Must be an http(s) URL of at most 500 characters after normalization; a bare domain is normalized to https. Null (or an empty string) clears it, keeping subscribers on the confirmation page branded with the company's name, logo, and colors.

Whether UTM parameters are appended to outbound links automatically. Enabling this with no stored parameters seeds the platform defaults.

Open tracking default for sends through the Send Email API. Account-wide open tracking must also be enabled; per-send trackingSettings can only opt out.

Click tracking default for sends through the Send Email API. Account-wide click tracking must also be enabled; per-send trackingSettings can only opt out.
