SendGrid API: what you can do and how to use it with AI agents
The SendGrid API, from Twilio, sends transactional and marketing email and manages templates, contacts, suppression lists and statistics. Product and marketing teams use it when they need reliable email at scale. Access is through an API key created in the dashboard, with configurable permissions.

Email sending
Transactional messages with personalization and attachments.
Dynamic templates
Templates with variables filled in at send time.
Contacts and lists
A marketing audience with segments and custom fields.
Suppressions
Unsubscribes, bounces and blocks that must not receive email.
Statistics
Deliveries, opens, clicks and failures by period or category.
Event webhook

What an iTeam agent does with the SendGrid API
Why did the customer not get it?
Support asks, and the agent checks the message activity and the suppressions, explaining whether it bounced, was blocked or was delivered.
Sending health
The agent tracks bounce and spam rates and warns the team before the domain reputation drops.
Personalized payment reminder
The agent prepares the email with a dynamic template and the invoice data, and sends it once finance approves.
Unsubscribes respected
People who ask to stop receiving email are added to the suppressions by the agent, so the request applies to every send.
From the credential to the agent at work, with approval
Create a restricted API key
In SendGrid, generate a key with only the permissions you need, such as sending and reading statistics.
Store it in the iTeam vault
The key stays in the vault, and each agent uses only approved templates and senders.
Test with approval
Bulk sends and new templates go through approval; known transactional emails can go straight out.

Questions about the SendGrid API
Is the SendGrid API free?
It depends on volume. There is an entry option with a low limit, and paid plans based on the number of emails.
Do I need to code to use the SendGrid API with iTeam?
Not necessarily. SendGrid is in the iTeam app catalog, and the deployment team sets up the workflows.
Can I tell whether an email was opened?
Yes, through the statistics and the event webhook, within the limits of open tracking in email clients.
