InboxAlly
InboxAlly
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. -

emailcampaign.ai
Email Campaign LLC
Most cold email tools assume the mailboxes, domains and DNS records already exist and already authenticate. emailcampaign.ai starts one step earlier. A daily sending target becomes a priced build, and one approval registers the sending domains, creates the mailboxes on Google Workspace, Microsoft 365 or dedicated servers, writes SPF, DKIM and DMARC and verifies every record against public resolvers, and warms each mailbox for two to three weeks before the first campaign. The same platform then runs the outreach: sequences within per-mailbox daily caps, a unified inbox that attributes each reply to the send it answers, reply classification, and inbox placement tests at Gmail and Outlook. For agencies a second product sits inside the first: a webmail on each client's own hostname, where the client's administrator connects a Google or Microsoft mailbox without sharing a password, masks addresses by policy, approves outbound forwarding rules and reviews deleted mail.Starting Price: $39/month -
7

Agencies and resellers can provision infrastructure programmatically through the REST API and webhooks.

Each email within a team inbox has its own activity panel to host internal conversations, contextual data, and time-stamped activity that enables team members to work with—and around—one message in place of forwards, reply-alls, and cc’s that bloat email volume. The Activity Panel lets you see automatically generated or manually applied message details like category tags, job references, and people involved, as well as who viewed the message, who replied, and how so. And collaboration is easy with the ability to tag others and add comments for real-time discussion. -
