Cold Email Infrastructure Across Every Provider
SuperSend builds and manages your entire cold email sending layer — domains, inboxes, warmup, routing, and placement — across Gmail, Outlook, private ESPs, and custom SMTP providers.
Why Deliverability Infrastructure Matters
Your outbound only works if your emails reach the inbox. SuperSend gives you the deliverability engine that keeps placement strong as you scale.

Placement Tests Across Every ESP

SuperSend sends alerts and stops volume increases automatically. You’ll see exactly which domain, DNS record, or inbox needs attention.
SuperSend tracks domain health, warm-up status, SPF/DKIM/DMARC signals, reply patterns, placement test results, and inbox reputation in real time.
Yes — if done incorrectly. High volume from a single inbox, sending too fast, or low-quality lists can trigger spam filters. SuperSend manages warmup, rotation, and reputation to prevent this.
A placement test sends emails to real mailboxes across Gmail, Outlook, Yahoo, and others to show whether your message lands in Inbox, Spam, or Promotions.
Warm-up runs automatically. SuperSend sends and interacts with emails in controlled patterns to build reputation, improve placement, and prepare inboxes for higher volume.
Yes. Cold email volume should never run through your primary domain. SuperSend provisions dedicated domains and inboxes so your main domain remains unaffected.
Most teams start with 2–5 inboxes per sender. This lets you safely send 50–125 cold emails per inbox per day while protecting domain reputation.
