Unisender MCP integration
Checks whether a specific email was delivered, subscribes contacts with field values and tags, maintains campaign templates, and processes opt-outs.
33actions available
Three actions you can hand over today
Every action runs live through MCP. Nothing to build, nothing to maintain.
Get campaigns
Lyro retrieves a list of campaigns from UniSender within a date range. Agents instantly see which campaigns are running and their performance timeline.
Subscribe contact to lists
Lyro adds a contact to mailing lists with tags and custom fields in one action. Support conversations enroll customers directly without a separate step.
Unsubscribe contact
Lyro removes contacts from UniSender lists when they request to opt out. Agents honor preferences immediately instead of flagging a manual task.
How businesses use Unisender + Lyro
Each card is one request a support team gets, and the Unisender actions Lyro runs to close it.
Answer whether an email actually arrived
Lyro checks the delivery status of a specific sent email by its ID, reads the campaign's progress and start time, and opens the contact record with the engagement history behind it.
Check Email StatusGet Campaign StatusGet ContactAdd someone to the right list properly
Lyro subscribes a contact to one or several lists with their tags and custom field values filled in, creates the list if it does not exist yet, and can import up to 500 contacts in one call.
Subscribe Contact to ListsCreate ListImport Contacts (Bulk)Keep campaign templates current
Lyro creates a reusable template with its subject, body, and sender details, revises only the fields that changed on an existing one, and adds the custom field a new personalisation needs.
Create Email TemplateUpdate Email TemplateCreate FieldProcess an opt-out the way it was asked
Lyro checks which lists a contact belongs to, then either unsubscribes them or excludes them from specific lists, picking the one that matches whether the request came from them or from your team.

How it works
Get started in 3 steps
Connect once, then just ask. There is no workflow builder to learn and nothing to maintain — Lyro reads the Unisender actions it has and picks the ones a request needs.
- 01
Connect Unisender
Authorize the Unisender account your team already uses — one consent screen, no API keys, no mapping tables. Lyro can only do what you granted that account, and you can disconnect it at any time.
- 02
Tell your agent what you need
Describe the job the way you would hand it to a teammate. Lyro maps it to the Unisender actions that close it and chains as many as the request needs.
- 03
Watch it work
The agent runs the actions inside the conversation the customer is already in, so nobody copies data between tabs and your team can take over at any point.

Everything else about Unisender
Setup, permissions, and the limits of what Lyro can do inside Unisender.
Unsubscribe Contact marks the contact as unsubscribed and only they can restore the active status by clicking an activation link, which makes it the right call for a customer-initiated opt-out. Exclude Contact from Lists removes them from lists and allows a later re-add through Subscribe Contact to Lists, which UniSender recommends when the sender is driving the change.
