Overview
Uplizd (specifically the PostSignup product) is an automated follow-up tool that sends personalized onboarding emails from your real Gmail or Microsoft 365 inbox. It connects via OAuth with "send only" permissions—it never reads your inbox, threads, or contacts. You set triggers (signup, trial, payment, inactivity) and the system sends plain-text, human-feeling emails automatically. Every sent email is logged in an audit log, giving you full visibility and control.

Core features
Send-only permissions
The tool uses Gmail's `gmail.send` scope or Microsoft 365's `Mail.Send`—it cannot read your inbox, drafts, threads, or contacts.
Trigger-based automation
Choose events like signup, trial start, payment, or inactivity to launch email sequences automatically.
Plain-text, personal emails
Emails are sent as plain text from your real address, avoiding marketing-style templates for a human feel.
OAuth with CSRF protection
One-click OAuth connection with cryptographically signed state parameters; no passwords stored, and you can revoke access anytime.
AES-256-GCM encryption
All OAuth tokens and sensitive data are encrypted at rest with regular key rotation.
Full audit log
See every email sent with timestamps, pause any playbook instantly, and export data anytime.
Daily send caps and throttling
Control how many emails go out per day to avoid overwhelming recipients.
Per-user suppression list
Automatically handle unsubscribes and suppress specific users from receiving further emails.
Target users
Founders, startup teams, and growth operators who need to send personalized onboarding emails without manual effort. It's built for security-conscious teams that want automation without giving a third party access to their inbox contents. Works for anyone using Gmail or Microsoft 365 and integrating with Stripe, Segment, or custom webhooks.
How to use
Connect your Gmail or Microsoft 365 inbox with one-click OAuth (send-only permission, no passwords). Then set triggers based on events like signup, trial, payment, or inactivity—using built-in templates or writing your own. The system automatically sends personalized plain-text emails from your real address. You monitor everything in the audit log, with controls to pause, cap daily sends, and manage suppression lists.
Effect review
Uplizd PostSignup solves a specific pain point: founders want to send personal onboarding emails at scale without sacrificing security or the human touch. The "send only, never read" permission model is a standout—it removes the privacy concern that plagues many email automation tools. The plain-text approach and trigger-based automation are straightforward and practical. For teams that value inbox security and want to maintain a founder-led voice in their onboarding, this tool delivers exactly what it promises. The integration with Stripe, Segment, and webhooks makes it flexible enough for most SaaS workflows.
