InboxAlly is an email deliverability platform for senders whose messages are landing in spam or promotions instead of the primary inbox. It repairs and protects sender reputation at the domain and IP level, warms up new domains and IPs on an adaptive schedule, and shows where messages actually land through inbox placement testing across Gmail, Outlook, Yahoo and other major mailbox providers. Live blacklist monitoring and deliverability alerts surface problems as they develop rather than after a campaign underperforms, and an ML-modeled sender score makes reputation measurable week to week.
InboxAlly runs alongside the stack you already have. It works with any ESP, SMTP service or custom sending infrastructure - including Mailchimp, SendGrid, Amazon SES, Brevo, Klaviyo, HubSpot and Instantly - with no migration and no change to how you send, and without handing over your sending credentials. A REST API and native integrations support programmatic setup, and separate sender profiles let agencies and multi-brand senders manage many domains side by side.
Based in New York, InboxAlly supports email marketers, agencies, cold outreach teams, SaaS senders and deliverability consultants, from a single domain to enterprise sending programs. Every plan includes a dedicated customer success manager and 24/7 live support, and evaluation starts with a 10-day free trial that requires no credit card.

OutMass
OutMass is a browser extension for Chrome and Edge that adds mass-email and mail-merge capability to Outlook on the web. Campaigns are built inside Outlook itself, and every message is sent through the user's own Microsoft account via the official Graph API, so recipients see a normal email rather than a bulk sender. Microsoft 365 and personal Outlook accounts are both supported. Campaigns start from a CSV: each column becomes a merge tag, and every recipient gets a personalized message. Open and click tracking show who engaged, and a daily reply check catches responses. Automated follow-ups re-contact non-openers and stop the moment someone replies. Scheduled sending, per-day send limits, A/B subject testing, an AI email writer, reusable templates, campaign reports with CSV export, unsubscribe links and OneDrive-link attachments complete the toolset. The interface is available in 13 languages. Free plan: 250 emails per month. Starter: $9/month for 2,500. Pro: $19/month for 10,000.
