Put an AI agent to work on your SendGrid email
Connect SendGrid in one click and delegate the busywork: an autonomous agent that keeps suppression lists clean, triages bounces and failures, reports deliverability, and turns email events into action across the rest of your stack. You set the autonomy, it does the work.

Fleece AI connects to SendGrid through managed OAuth and lets autonomous agents send transactional email, manage dynamic templates, watch event webhooks, curate suppression lists, and monitor deliverability in real time. Agents combine SendGrid with 3,000+ other apps — Gmail, Google Sheets, Slack, HubSpot — so a bounce, a spam report, or a delivery failure can become a cleaned list, a Slack alert, or a CRM update anywhere in your stack, under the approval rules you set.

What a Fleece agent does with SendGrid
SendGrid is the pipe your product email runs through — password resets, receipts, notifications, and marketing sends all leave the building via its transactional API and dynamic templates. When it works, no one notices; when a domain's deliverability slips, bounces spike, or spam reports climb, you find out late and from angry users. The signals are all there in SendGrid's event webhooks and activity feed, but nobody has time to watch them. A Fleece agent does. It reads the events you point it at, understands what a delivered, opened, bounced, dropped, or spam-reported event means in context, and acts — cleaning, alerting, reporting, or escalating, according to the instructions you give it in plain language.
Under the hood, the connection runs through managed OAuth — you authorize SendGrid once, and Fleece handles the API credentials, scopes, and refresh securely. The agent can send transactional email through templates, populate dynamic template data, read and edit suppression groups (bounces, blocks, spam reports, invalid addresses, unsubscribes), pull stats on opens, clicks, bounces, and blocks, and subscribe to event webhooks. Event triggers let it react the moment a hard bounce, a spam report, or a delivery failure lands — no polling a stats endpoint on a timer, no waiting for a daily export.
What makes this different from SendGrid's built-in automations and template logic is judgment. SendGrid can send on a schedule and suppress a hard bounce, but it cannot read a spike of soft bounces from one domain, decide it looks like a reputation problem rather than a bad list, and coordinate the fix across your other tools. A Fleece agent can — and because Fleece agents work as a hierarchy, a lead agent delegating to specialized child agents, one SendGrid-facing agent can hand analysis to a data agent, list reconciliation to a CRM agent, and reporting to a Slack-facing agent, then summarize the outcome.
What the agent can do in SendGrid
Suppression and bounce hygiene
Curates suppression groups with judgment — pruning stale hard bounces, keeping genuine unsubscribes, and flagging patterns that look like a list or reputation problem.
Deliverability reporting
Assembles digests of opens, clicks, bounces, and blocks by domain or template, and surfaces the drift that matters instead of a wall of raw stats.
Transactional-failure triage
Watches event webhooks for dropped and bounced sends, works out whether it is a template, a domain, or a recipient problem, and raises the right alert.
List and segment coordination
Keeps SendGrid suppression state in sync with your CRM segments so a hard bounce or unsubscribe is reflected everywhere, not just in one tool.
Real-time triggers
Reacts the moment a bounce, spam report, or delivery failure event fires, through event-based webhooks rather than polling a stats endpoint.
Approval gates
Anything sensitive — sending a broadcast, deleting a suppression entry, editing a template — pauses for your one-click sign-off before it happens.
Automations teams run on SendGrid
These are concrete setups you can describe to a Fleece agent in plain language. Each one combines SendGrid with other connected apps.
Deliverability: keep suppression lists clean without guessing
The agent watches SendGrid's event webhooks and reviews suppression groups on a schedule. It prunes stale hard bounces and blocks, but it does not blindly delete — genuine unsubscribes and spam-report entries stay put, and anything ambiguous is logged to a Google Sheets review list with the reason. When it spots a cluster of bounces from a single recipient domain, it flags a possible reputation issue rather than quietly removing addresses, so you fix the cause, not just the symptom.
Ops: deliverability digest to Slack every morning
Each morning the agent pulls SendGrid stats — opens, clicks, bounce rate, block rate — by template and sending domain, compares them against the prior period, and posts a short deliverability digest to your Slack #email channel. It leads with what changed: a template whose bounce rate doubled, a domain whose opens dropped. Instead of anyone logging into the dashboard to read charts, the drift comes to the team where they already work.
Support: real-time triage of transactional failures
When a hard bounce or dropped event fires for a transactional send — a password reset or receipt that never arrived — the agent reacts in seconds. It works out whether it is an invalid address, a suppressed recipient, or a template error, posts an alert to Slack with the classification, and for customer-facing failures drafts a follow-up through Gmail for the support team to approve. A silent delivery failure becomes a tracked, explained incident.
Marketing: keep SendGrid and HubSpot in step
The agent reconciles SendGrid suppression state with HubSpot segments so the two never drift apart. When a contact hard-bounces or files a spam report in SendGrid, it updates the matching HubSpot property and removes them from active send segments; when HubSpot marks a contact unsubscribed, it mirrors that into the SendGrid suppression group. List hygiene stays consistent across both tools without a manual export-and-import cycle.
How to connect SendGrid to Fleece AI
Create your Fleece account
Sign up and start the 7-day trial. You land in a workspace where agents, flows, and integrations live together.
Connect SendGrid via managed OAuth
Pick SendGrid from the integrations catalog and authorize it in one click. Fleece manages credentials and scopes for you; you can revoke access at any time from SendGrid or from Fleece.
Describe the job in plain language
Create an agent and tell it what to watch and what to do — "prune stale hard bounces weekly, alert Slack on any spam-report spike, keep HubSpot segments in sync". No pipeline diagram to build.
Set autonomy and approval gates
Choose what the agent may do on its own and what waits for your sign-off. Sensitive actions — broadcasts, suppression deletions, template edits — pause for one-click approval.
Run it on triggers or a schedule
Let the agent react to SendGrid event webhooks in real time, or schedule recurring flows — morning deliverability digests, weekly list hygiene — that run without you.
SendGrid works better with the rest of your stack
SendGrid automations get powerful when they cross app boundaries. Pair SendGrid with Slack to push deliverability digests and failure alerts to your team, with Google Sheets to log suppression reviews and bounce history for auditing, with HubSpot to keep segments and suppression state in sync, or with Gmail to draft customer follow-ups when a transactional send fails — all through the same agent, all under the same approval rules. Fleece connects to 3,000+ apps, so the stack you already use around your email is almost certainly covered.
