Agencies live and die by email. Proposals sent, responses awaited, follow-ups timed. But most free email tracking tools are built for solo users: they don't account for multiple Gmail accounts, client-specific tracking, or the need to share engagement data with your team.

Here's how agencies and small teams can use TrackMailBox effectively without complicated setup or paid plans.

Managing Multiple Gmail Accounts

Many agencies use separate Gmail or Google Workspace accounts (one per client, one for BD, one for internal communication). TrackMailBox supports multiple accounts, but there are a few things to keep in mind:

• One active account per Chrome profile: TrackMailBox tracks emails sent from whichever Google account is active in the current Gmail session. If you switch Gmail accounts, confirm the TrackMailBox extension is signed into the matching account.
• Chrome profiles for separation: The cleanest setup for multi-account agencies is Chrome's built-in profile feature. Create a separate Chrome profile for each Gmail account, install TrackMailBox in each, and sign into the correct account in each profile. You'll have separate dashboards, separate tracking data, and no cross-contamination.
• Account mismatch warning: If TrackMailBox detects that the active Gmail account doesn't match the signed-in TrackMailBox account, you'll see a mismatch prompt. Click it to re-authenticate rather than ignoring it, as mismatched sessions can cause missed tracking.

Tracking Client Proposals and Deliverable Emails

For agencies, proposal emails are high-stakes. Knowing when a client opened your proposal, and how many times, directly informs whether to follow up, hold off, or escalate.

Recommended setup for proposal tracking:

1. Include a tracked link to the proposal document. A Google Doc or PDF link, tracked through TrackMailBox, tells you not just that they opened the email but that they clicked into the proposal itself. A click is far stronger signal than an open.
2. Name your emails clearly. The TrackMailBox dashboard shows email subjects. Use descriptive subjects so you can quickly identify which proposal is which in your tracking view.
3. Note the timing of opens. A proposal opened 5 times in 3 days means the client is actively evaluating it, possibly showing it to decision-makers. A proposal opened once and never revisited may need a follow-up call.
4. Track the invoice email too. Knowing when a client opened your invoice (vs. claiming they never received it) is practically useful for payment follow-ups.

Using Templates for Repeatable Outreach

Agencies frequently send similar email types repeatedly: initial outreach, proposal covers, project update summaries, feedback requests. TrackMailBox works alongside Gmail's template feature:

Link Tracking for Portfolio and Proposal Assets

For agencies, the links in your emails often matter more than the email body. A prospect who clicks your portfolio link, then re-clicks it 3 times in a week, is significantly more interested than someone who opened your email once.

High-value links to track in agency outreach:

• Portfolio / case study link: Know which clients engage with your work samples
• Proposal document: Confirm the proposal was actually reviewed, not just received
• Pricing page or service deck: A pricing click signals commercial intent
• Calendar booking link: Know when someone is trying to find time before they confirm
• Client testimonial or reference page: Understand if prospects are doing due diligence on you

Sharing Tracking Data with Your Team

TrackMailBox is currently a single-user tool: there isn't a shared team dashboard where multiple accounts contribute to a unified view. For agencies working with a small team, here are practical workarounds:

Screenshot sharing: For important proposals, screenshot the TrackMailBox dashboard view for that email and share in Slack or your project management tool. Gives the team visibility without needing shared access.

Dedicated tracking account: For client-facing emails that the team shares responsibility for, use a single shared Gmail account with TrackMailBox installed. All tracked outreach from that account is visible in one place.

Weekly summary update: Whoever manages business development does a weekly review of tracked proposal emails and posts a status update to the team: which proposals have been opened, how many times, and what the next follow-up action is.

Tracking Outreach Performance Over Time

After a few weeks of tracking, your TrackMailBox dashboard becomes a record of your outreach patterns. Use the date-range filter to analyze:

• Which types of subject lines get the most opens
• Which time slots generate the fastest opens (Tuesday 9 AM vs Thursday 2 PM)
• Which proposal emails generated link clicks (engaged) vs open-only (passive)
• How long the average proposal takes from first open to response

This data is more actionable than any generic "email best practices" article because it's based on your actual recipients, your actual industry, and your actual templates.

Frequently Asked Questions

Can multiple team members use the same TrackMailBox account?

TrackMailBox is designed for individual use: each person signs in with their own Google account. For teams, the practical approach is for each team member to install TrackMailBox on their own Chrome profile with their own account. There isn't currently a shared team dashboard, but you can share tracking screenshots or use a dedicated shared Gmail account for team outreach.

Does TrackMailBox work with Google Workspace accounts?

Yes. TrackMailBox works with both personal Gmail accounts and Google Workspace (formerly G Suite) accounts. Install the extension, sign in with your Workspace account, and tracking works the same way as with a personal Gmail.

Can I track emails sent on behalf of a client?

If you have access to the client's Gmail account (via shared login or delegated access), you can install TrackMailBox and send tracked emails from that account. The tracking data will appear in the TrackMailBox dashboard associated with that account. Confirm the extension is signed into the correct account before sending.

How do I know which proposal email a client opened?

The TrackMailBox dashboard shows the email subject line, recipient, and open/click timeline for each tracked email. Use descriptive subject lines like "Proposal: [Client Name] - Web Redesign 2026" so you can immediately identify the right email in your dashboard view.

Can I export tracking data to share with a client or manager?

TrackMailBox's dashboard allows you to view detailed open and click history per email. For sharing, the current approach is to screenshot or manually summarize the data. A more structured export feature is on the product roadmap. For now, the dashboard serves as your tracking record.
