Investor Inbox Management: Stay on Top of Every Deal and Portfolio Update

Investor inbox management is a competitive edge. The investor who responds fastest to a compelling inbound, who follows up on a founder update within 24 hours, who catches an LP question before it becomes a concern — that's the investor founders want to work with. Sifta gives you that speed without requiring you to live in your inbox.

Sound Familiar?

Inbound deal flow is unpredictable — it could arrive at any time of day, competing with portfolio communications, LP emails, and conference correspondence.

Founders notice response time. A delayed reply during a critical fundraising moment sends the wrong signal about how engaged you'll be as an investor.

High-volume inboxes mean real opportunities sometimes sit for hours before you see them — in a fast market, that's enough time to lose a deal.

How Sifta Fixes This

✓

Sifta learns your portfolio and high-priority network, ensuring communications from founders, co-investors, LPs, and key contacts surface immediately via iMessage.

✓

High-signal inbound deal flow — warm intros, compelling founder emails, time-sensitive opportunities — is flagged even from senders you've never interacted with.

✓

You get a concise summary of every important email within seconds of arrival, with enough context to decide whether to respond now or schedule it for later.

What You Get

First response to deal flow in minutes, not hours

Founder updates never go unacknowledged for days

LP communications are caught and handled promptly

Strong response-time reputation, built without inbox addiction

Frequently Asked Questions

Can I mark my entire portfolio as high priority? +

Yes. You can add domains or contacts as high-priority during setup, ensuring any email from your portfolio founders is immediately surfaced.

How does Sifta distinguish a warm intro from cold outreach? +

Sifta reads the full email content. A warm intro from a mutual contact in the body of the email is treated differently from a generic cold pitch, even if they look similar at the subject-line level.

What if I'm in LP meetings or off-site and can't respond? +

You'll still receive the alerts and summaries. You can decide from the text whether to act immediately, flag for follow-up, or let it sit until you're free — without opening your inbox.

Does Sifta work with Outlook or just Gmail? +

Gmail is supported in the current version. Outlook support is planned for a future release.
