Productivity and Infrastructure
InboxKit is essentially email infrastructure as a service built for cold outreach at scale. You can buy or connect domains, then provision Google Workspace and/or Microsoft 365 mailboxes, with DNS, authentication, and warmup workflows handled for you, and manage it all from a single place.
Fed up with the quirks of New Outlook?With this simple and lightweight app for Windows, you can drag emails and attachments directly into any Windows application or web page!
No more downloading to your desktop first. At last!
Another epic “email infrastructure as a service”, perfect for launching domains dedicated to outbound emails from Google or 365 accounts spun up in minutes. Connect to your outreach tools with one click and away you go!
This is our absolute “secret weapon” when assessing the reputation of domains, emails and content. Run inbox placement tests to see where your emails land and get insights on the structure and content of your emails. Absolute game changer.
If your emails are routing through your web host or a basic ISP mail server, you’re already at a disadvantage. SMTP2GO is a dedicated outbound email relay that routes your email through purpose-built, globally distributed infrastructure. No arbitrary sending limits, and proper SPF and DKIM handling out of the box.
For recruitment agencies sending at volume, the reporting alone makes it worthwhile. You get full visibility on every sent email (bounces, spam complaints, open tracking) so deliverability issues surface quickly
Campaign Monitor is a clean, well-regarded email marketing platform built around ease of use without sacrificing capability. The drag-and-drop builder produces good-looking emails without touching code, and the automation features let you build sequenced journeys that run without manual intervention — useful for recruitment agencies running nurture campaigns alongside direct outreach.
Where it earns its place from a deliverability perspective is its managed sending infrastructure. You’re not routing campaigns through your own domain reputation — Campaign Monitor handles the heavy lifting on deliverability, with SPF and DKIM alignment built in.
Solid choice if you want a reliable platform that stays out of your way and keeps your emails looking professional.
