Dynosend is an email marketing platform for managing audiences and contacts, operating campaigns, sending transactional messages, and tracking customer events.

## Tools

- **Add Email To Blacklist** — Permanently add an email address to the Dynosend blacklist. This cannot be undone through the Dynosend API because Dynosend exposes no removal operation.
- **Add Tags To Contact** — Append one or more tags to a contact without replacing its existing tags.
- **Check Blacklist** — Check whether an email address is on the connected Dynosend account's blacklist and return its timestamp and reason when available.
- **Create Contact** — Create a contact in an audience, optionally assigning tags and audience-defined custom fields. Can bypass double opt-in when explicitly requested.
- **Delete Contact** — Permanently delete one contact from an audience for GDPR/CCPA erasure. This destructive operation cannot be undone.
- **Find Duplicate Contacts** — Find contacts that use the same email address across all audiences in the connected Dynosend account.
- **Get Audience** — Get one audience's configuration, custom-field definitions, contact information, and subscription statistics by audience UID.
- **Get Campaign** — Get one campaign's configuration and delivery, open, click, spam, bounce, and unsubscribe insights.
- **Get Contact** — Get one contact in an audience by contact UID or email address.
- **List Audiences** — List audiences available to the connected Dynosend account, including the UID needed by audience and contact tools.
- **List Campaigns** — List campaigns in the connected Dynosend account, including status and the campaign UID used by campaign tools.
- **List Contacts** — Return one page of contacts in a Dynosend audience, including contact UIDs, subscription status, tags, and audience-defined custom-field values.
- **Record Contact Event** — Record an application event for a contact in an audience. Dynosend stores the event persistently for automations and segmentation, and its API does not provide an operation to delete recorded events.
- **Send Transactional Message** — Send a configured Dynosend transactional message. This immediately sends email and may create the recipient as a new Dynosend contact if the address is unknown.
- **Set Campaign Delivery State** — Pause a sending campaign or resume a paused campaign by setting its delivery state to paused or sending. Resuming can send queued emails to campaign recipients; this does not start a ready campaign.
- **Set Contact Subscription Status** — Set a contact's subscription status to subscribed or unsubscribed in an audience.
- **Start Campaign** — Start a ready broadcast campaign. This immediately sends email to all campaign recipients and cannot be undone.
- **Update Contact** — Update a contact's email, replace its complete tag set, or set audience-defined custom fields.
