Email that never reaches the primary inbox never gets read. InboxAlly is a deliverability platform built for senders who need to recover inbox placement and then hold it. It repairs sender reputation at the domain and IP level, runs adaptive warmup for new sending identities, confirms where mail is landing with placement testing across Gmail, Outlook, Yahoo and more, and raises alerts when blacklist status or reputation trends move the wrong way. An ML-modeled sender score turns reputation into a number you can track week to week rather than a guess. InboxAlly adds to your existing setup instead of replacing it. It works with any ESP, SMTP relay or custom sending infrastructure, needs no migration, and does not require your sending credentials. It scales from one domain to enterprise programs running many sender profiles, with a REST API, native integrations, a dedicated customer success manager on every plan, and 24/7 live support.

StackAI is an enterprise AI automation platform built to help organizations create end-to-end internal tools and processes with AI agents.

Using its visual workflow builder, teams can map entire processes — from data intake and enrichment to decision-making, reporting, and audit trails. Enterprise knowledge bases such as SharePoint, Confluence, Notion, Google Drive, and internal databases can be connected directly, with features for version control, citations, and permissioning to keep information reliable and protected. AI agents can be deployed in multiple ways: as a chat assistant embedded in daily workflows, an advanced form for structured document-heavy tasks, or an API endpoint connected into existing tools. StackAI integrates natively with Slack, Teams, Salesforce, HubSpot, ServiceNow, Airtable, and more. Security and compliance are embedded at every layer. The platform supports SSO (Okta, Azure AD, Google), role-based access control, audit logs, data residency, and PII masking. Enterprises can monitor usage, apply cost controls, and test workflows with guardrails and evaluations before production. StackAI also offers flexible model routing, enabling teams to choose between OpenAI, Anthropic, Google, or local LLMs, with advanced settings to fine-tune parameters and ensure consistent, accurate outputs. A growing template library speeds deployment with pre-built solutions for Contract Analysis, Support Desk Automation, RFP Response, Investment Memo Generation, and InfoSec Questionnaires. By replacing fragmented processes with secure, AI-driven workflows, StackAI helps enterprises cut manual work, accelerate decision-making, and empower non-technical teams to build automation that scales across the organization.
