How to manage Gmail, Slack and LinkedIn messages in one inbox

The real cost of five inboxes

Most people who work with clients now get requests in at least three places: email, a team chat like Slack, and LinkedIn. Each app is fine on its own. The problem is between them: a request in Slack doesn't show up in your email routine, a LinkedIn reply from a lead sits unread for a week, and nobody has a single view of what's waiting.

Your options, from free to fully unified

Option 1: Forward everything to email (free)

• Slack: turn on email notifications for direct messages and mentions (Preferences → Notifications → “When I'm not active on desktop”).
• LinkedIn: turn on email notifications for messages (Settings → Notifications → Messages). LinkedIn then emails you each new message.

Everything now arrives in one email inbox. The downside is noise: notifications are mixed with real email, you can't reply from them, and nothing tells you which ones matter.

Option 2: Email filters and labels (free)

Add filters that label the notification emails (“from:linkedin.com subject:message” → label LinkedIn) so you can review them as a group. It cuts noise, but you still triage everything yourself.

Option 3: A unified inbox app

A unified inbox connects to each service through its official API and shows the conversations side by side. What to look for:

• Official connections only. It should use Google's, Microsoft's and Slack's own permission screens. Avoid anything that asks for a password or logs in to a personal account through a browser.
• Honest LinkedIn support. LinkedIn doesn't offer a public messaging API. Tools that claim full LinkedIn inbox access usually automate your session, which breaks LinkedIn's terms and can get your account restricted.
• Priority, not just a merged list. Merging five noisy feeds into one bigger feed doesn't help. You want what needs you on top, with a reason.
• You approve every send. If AI writes replies, it should never send them on its own.

How Senvoro does it

Senvoro connects Gmail, Outlook and Slack through their official APIs, and reads LinkedIn messages from the notification emails LinkedIn already sends you. Replies to LinkedIn open the right conversation on LinkedIn with your text ready to paste, so your LinkedIn account is never logged into by anyone else. See exactly what each connection can and can't do on the integrations page.

Everything lands in one inbox split into Needs you, Worth reading and Newsletters & updates. Each conversation shows why it's there, and threads about the same thing in different apps are linked. You can try the demo without signing up.

Quick setup checklist

1. List every place people send you work requests.
2. Turn on LinkedIn message emails so LinkedIn has an email trail.
3. Decide where you'll triage: your email client with filters, or a unified inbox.
4. Turn off push notifications in the individual apps, so you aren't pinged twice.
5. Review the combined view at fixed times, not all day.
