For Agents

Manage Everlytic contacts and lists, retrieve campaign messages, and send transactional email or SMS for marketing and product notification workflows.

Connect the Everlytic API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Everlytic API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Install Jentic One Beta (Self-Hosted)

Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

View OpenAPI Document

The Everlytic API is the programmatic surface for Everlytic's email marketing, SMS, and push notification platform. Fourteen operations across 7 paths cover contact and list management, campaign messages, and transactional email and SMS sends. Authentication is via HTTP Basic, and the API is the right surface for syncing customer data from CRMs and product systems into Everlytic, triggering transactional messages from app events, and powering AI agents that send branded communications on demand.

Use Cases

Patterns agents use Everlytic API API for, with concrete tasks.

★ CRM to Everlytic Sync

Mirror contacts from a CRM into Everlytic so marketing campaigns always run against the latest segments. The /contacts and /lists endpoints provide create, read, update, and delete operations needed for two-way sync. A working sync takes a day or two and removes the manual CSV imports that marketing teams typically perform monthly.

On every CRM contact update, POST /contacts to Everlytic if new or PUT /contacts/{id} if existing, and add to the matching list via /lists/{id}

Transactional Email Triggers

Trigger transactional emails from product events such as 'order shipped' or 'password reset' by calling /transactional/email with a templated payload. This keeps transactional sends inside the same platform as marketing sends, simplifying analytics and unsubscribe handling. Setup typically takes a single afternoon.

When a new order ships, POST /transactional/email with the customer's email, template ID, and order tracking number

SMS Reminders for Appointments

Send SMS appointment reminders or two-factor codes through /transactional/sms, replacing a separate SMS gateway. The API accepts the destination number and message and returns a send identifier for receipts. This collapses two vendors into one for South African and African market deployments where Everlytic is widely used.

Send an SMS via /transactional/sms to a customer with their appointment time and a confirmation link

AI Agent Integration via Jentic

Wire Everlytic to an AI assistant through Jentic so internal staff can send a transactional email or SMS in chat without leaving Slack. Jentic search resolves the intent to the right Everlytic operation and the vault holds the credentials. Setup takes minutes once Everlytic is connected.

Search Jentic for 'send everlytic transactional email', load the POST /transactional/email operation, and send a templated message captured from chat

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Everlytic Basic Auth credentials sit encrypted in the Jentic vault. Agents call operations through scoped execution tokens, so the raw username and password never enter the model context.

Intent-based discovery

Agents search Jentic by intent (e.g., 'send everlytic transactional email') and Jentic returns the matching operation with its schema, so the agent sends only the recipient and template fields.

Time to first call

Direct integration: 1-2 days for contact sync, send wrappers, and credential rotation. Through Jentic: under 30 minutes from sign-up to first executed send.

FAQs

Specific to using Everlytic API API through Jentic.

What authentication does the Everlytic API use?

The Everlytic API uses HTTP Basic authentication. Through Jentic, the credentials sit in the encrypted vault and are injected at execution time, so the raw username and password never enter the agent's context.

Can I send transactional emails through the Everlytic API?

Yes. POST /transactional/email sends a single transactional email with a template and per-recipient merge fields. This is suited to order confirmations, password resets, and other product-driven sends that should share analytics with marketing campaigns.

What are the rate limits for the Everlytic API?

The OpenAPI spec does not declare explicit rate limits. Treat the API as standard for an email service provider, back off on HTTP 429, and consult Everlytic's developer documentation for current published limits before bulk sends.

How do I sync contacts to Everlytic through Jentic?

Search Jentic for 'everlytic create contact' and 'everlytic add to list', load the POST /contacts and /lists/{id} operations, and execute them in sequence. Install with pip install jentic and use the async search, load, execute pattern.

Does the Everlytic API support SMS sends?

Yes. POST /transactional/sms sends a single SMS to a destination number with the message body. This is widely used for appointment reminders and 2FA codes in markets where Everlytic is the established provider.

Can I manage list subscriptions via the API?

Yes. /lists and /lists/{id} cover list-level CRUD, and contact list membership is managed through the contacts and lists endpoints. This is the right surface for syncing CRM segments into Everlytic without touching the dashboard.
