GET/v1/senders

Returns a paginated list of the email and LinkedIn senders that sequences send from, archived ones included, ordered by createdAt descending. Use offset and limit to paginate, and bracketed filters to narrow the list.

Supported filters: channel[equal] (EMAIL, LINKEDIN), health[equal] (UNVERIFIED, HEALTHY, UNHEALTHY), owner[equal] (a member ID), and archived[equal] (true, false). Filters are combined with AND.

Required scope: senders:read

ReturnsExpand Collapse
SenderListResponse object { data, object, totalCount }
data: array of object { id, archivedAt, channel, 9 more }
id: string

Unique identifier of the sender.

archivedAt: string

When the sender was archived, or null if it is active. Archived senders never send.

channel: "EMAIL" or "LINKEDIN"

Whether this sender sends email or LinkedIn messages.

One of the following:
"EMAIL"
"LINKEDIN"
createdAt: string

When the sender was created.

emailAddress: string

The address email from this sender is sent from. Null for LinkedIn senders, or when the connected account has no address.

health: "UNVERIFIED" or "HEALTHY" or "UNHEALTHY"

HEALTHY can send. UNHEALTHY cannot send until healthReason is resolved. UNVERIFIED means no health verdict yet: an email sender in this state cannot send until it passes a health check, while a LinkedIn sender is never health-checked, so a working LinkedIn sender is usually UNVERIFIED and can send.

One of the following:
"UNVERIFIED"
"HEALTHY"
"UNHEALTHY"
healthReason: string

Why the sender is UNHEALTHY or UNVERIFIED, for example ACCOUNT_DISCONNECTED, BOUNCE_THRESHOLD or INVITE_LIMIT; null when healthy.

objectType: "sender"

Always sender.

owner: string

Member ID of the person who owns this sender, or null when no workspace membership can be resolved.

pacing: object { EMAIL, LINKEDIN_INVITE, LINKEDIN_MESSAGE }

How this sender paces each step type it sends, keyed by sequence step type: EMAIL for an email sender; LINKEDIN_INVITE and LINKEDIN_MESSAGE for a LinkedIn sender.

EMAIL: optional object { dailyLimit, maxGapSeconds, minGapSeconds }

Email steps. Present only on an email sender.

dailyLimit: number

Most sends of this step type in any rolling 24 hours.

minimum-9007199254740991
maximum9007199254740991
maxGapSeconds: number

Upper bound of the minimum spacing, in seconds. Before each send, a minimum spacing is drawn at random between minGapSeconds and this value, and the send waits until that long after the previous one. Sends can be further apart, for example outside the send window or once dailyLimit is reached. Null means the minimum spacing is always minGapSeconds.

minimum-9007199254740991
maximum9007199254740991
minGapSeconds: number

Lower bound of the minimum spacing between two of its sends, in seconds.
