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.

Zaymo
Zaymo is an interactive email marketing platform designed to help ecommerce brands turn traditional emails into dynamic, conversion-driven experiences that function more like mini storefronts inside the inbox. It enables marketers to build these experiences using a no-code builder, allowing them to add interactive widgets such as one-click upsells, embedded product blocks, review forms, surveys, SMS sign-ups, and subscription management tools directly into existing email templates. Instead of redirecting users to external websites, Zaymo allows customers to perform actions like shopping, leaving reviews, answering surveys, or modifying subscriptions without leaving their email, significantly reducing friction in the conversion process. It integrates with tools like Shopify and Klaviyo, making it easy to import existing campaigns, enhance them with interactive elements, and deploy them quickly.
