Sending Emails from Slack Using OpenClaw and Gmail

Why Email and Slack Should Work Together

If you've spent any time managing a busy team, you already know the frustration: a conversation happens in Slack, a decision gets made, and then someone has to context-switch over to Gmail to actually act on it. Copy the recipient, remember the thread, write the email, come back and report. It's a small thing, but it adds up fast across dozens of interactions every week.

SlackClaw changes that dynamic. Because it runs OpenClaw — an open-source AI agent framework — directly inside your Slack workspace, your team gets an autonomous agent that can do things, not just answer questions. Sending an email to a client is just one example. The same agent can also file a bug in Linear, update a Notion doc, or open a pull request on GitHub. But for this guide, we're going to focus squarely on Gmail, and how to get your SlackClaw agent composing and sending emails on your behalf in just a few minutes.

Connecting Gmail in One Click

SlackClaw connects to over 800 tools through one-click OAuth, and Gmail is one of them. There's no API key hunting, no JSON credential files to download, and no service account configuration to wrestle with. Here's how to get it set up:

1. Open your SlackClaw dashboard and navigate to Integrations.
2. Search for Gmail in the integrations list.
3. Click Connect and follow the OAuth prompt — this takes you through Google's standard permission screen.
4. Grant the scopes SlackClaw requests (send mail, read mail, manage labels — depending on what you want your agent to do).
5. You'll be redirected back to the dashboard with Gmail showing a green "Connected" status.

That's it. Your SlackClaw agent now has the ability to interact with Gmail on behalf of whoever authenticated. If you're connecting a shared team address (like support@yourcompany.com or hello@yourcompany.com), just make sure the right Google account is signed in when you go through the OAuth flow.

Sending Your First Email from Slack

Once Gmail is connected, you can start sending emails directly from any Slack channel or DM where SlackClaw is present. The agent understands natural language, so you don't need to remember any special syntax.

Try typing something like:

@SlackClaw Send an email to sarah@clientco.com letting her know the project proposal is ready for review and we're targeting a Thursday kickoff call.

The agent will draft the email, show you a preview in Slack, and ask for confirmation before sending. This confirmation step is intentional — it keeps humans in the loop for outbound communication, which matters when you're sending on behalf of a professional account.

The preview will look something like this inside Slack:

📧 Draft Email
To: sarah@clientco.com
Subject: Project Proposal Ready for Review

Hi Sarah,

I wanted to let you know that the project proposal is now ready for your review. We're targeting a Thursday kickoff call — please let me know if that timing works for you.

Looking forward to connecting!

Click Send and the email goes out through Gmail. The thread stays logged in your SlackClaw conversation history, so there's a record of what was sent and when.

Using Persistent Memory to Personalize Emails

Here's where SlackClaw starts to pull ahead of simpler automation tools. Because each team runs on a dedicated server with persistent memory, your agent actually remembers context over time. You don't have to re-explain who your clients are or how your team communicates every time you start a new session. Learn more about our pricing page.

For example, if you previously told SlackClaw:

"We always sign off emails with 'Best regards, The Acme Team' and we prefer a friendly but professional tone." Learn more about our integrations directory.

...it will apply that consistently to every email it drafts going forward. You can also store things like:

• Client names and their preferred communication style
• Common email templates (invoices, status updates, follow-ups)
• Contacts to CC by default on certain types of emails
• Your team's email signature

This makes the agent genuinely useful day-to-day rather than just a novelty. After a few interactions, it starts to feel less like issuing commands and more like working with a capable colleague who already knows the context.

Building Multi-Step Workflows Around Email

One of the more powerful patterns with SlackClaw is chaining Gmail actions into larger workflows. Because the agent can work across all of your connected tools simultaneously, a single prompt can kick off a sequence that spans multiple systems.

Example: Client Status Update Workflow

Suppose your team closes out a sprint and you want to notify a client. Instead of manually pulling data from Jira, writing an email, and updating your Notion project tracker, you could type:

@SlackClaw Pull the completed tickets from the Acme project in Jira, write a friendly status update email to the client contact on file, and update the Notion project page with a "Sprint 4 Complete" status.

The agent will:

1. Query Jira for completed issues in that project
2. Draft an email summarizing the work done
3. Show you the email preview for approval
4. Send the email via Gmail after confirmation
5. Update the Notion page in parallel

This kind of cross-tool coordination used to require either a dedicated operations person or a complex Zapier chain. With SlackClaw, it's a single natural language instruction.

Example: Auto-Responding to Support Inquiries

If you've granted SlackClaw read access to your Gmail inbox, you can also build lightweight monitoring workflows. For instance:

@SlackClaw Check our support inbox and let me know if there are any emails that have been waiting more than 24 hours without a reply.

The agent will scan the inbox, identify threads with no outbound reply in the last 24 hours, and surface them in Slack with a summary. You can then respond from Slack directly, or ask the agent to draft replies for your review.

Creating Custom Skills for Repeated Email Tasks

If there's an email task your team does frequently — sending weekly reports, notifying stakeholders of deployments, following up on unpaid invoices — you can turn that into a custom skill inside SlackClaw.

Custom skills let you define reusable agent behaviors with a name and a set of instructions. For example, a skill called Send Deployment Notice might be configured to: For related insights, see OpenClaw Slack Performance Tuning: Faster Response Times.

• Pull the latest release notes from GitHub
• Format them into a readable email
• Send to your stakeholder distribution list
• Post a summary in the #deployments Slack channel

Once the skill is created, any team member can trigger it with a simple command like @SlackClaw run Send Deployment Notice. No one needs to remember the full prompt or the specific steps — the agent handles it consistently every time.

A Note on Pricing and Team Access

SlackClaw uses credit-based pricing rather than per-seat fees, which makes it particularly well-suited for teams where not everyone uses the agent at the same volume. A developer who triggers a deployment email once a week uses far fewer credits than an account manager who's composing client communications daily — and your billing reflects that actual usage rather than a flat head count charge.

Because the agent runs on a dedicated server per team, the Gmail connection and any stored memory are isolated to your workspace. Your client contact list and email drafts aren't commingled with any other team's data, which matters if you're operating in a regulated industry or simply care about clean data boundaries.

Getting the Most Out of Gmail + SlackClaw

A few practical tips to make your Gmail integration as effective as possible: For related insights, see Connect Gmail to OpenClaw for Email Automation in Slack.

• Store your contacts in SlackClaw's memory early on. Tell the agent who your key clients, vendors, and stakeholders are, and it will be able to address emails correctly without you specifying every time.
• Use labels in Gmail to help the agent filter and prioritize. Asking it to "check the Urgent label" is faster than scanning the full inbox.
• Pair Gmail with Linear or Jira for engineering teams — when a bug is marked critical, the agent can automatically draft a heads-up to the relevant client contact for your review.
• Always use the preview step before sending to a new contact for the first time. The agent is good, but a quick human review on first contact builds good habits.
• Build skills for templated emails — invoices, onboarding sequences, weekly reports — so the quality stays consistent regardless of who triggers them.

The goal isn't to remove humans from your email communication — it's to remove the tedious parts so your team can focus on the decisions that actually require judgment. SlackClaw handles the drafting, the routing, and the coordination. You stay in control of what goes out the door.

If you haven't connected Gmail yet, head to your SlackClaw integrations dashboard and give it a try. The whole setup takes under five minutes, and you'll probably find a use for it before the day is out.
