Stop guessing if your emails land in spam. Learn how to implement ongoing placement testing to monitor deliverability and protect your sending infrastructure.
Without placement testing, you only see open rates, which are unreliable. You can't tell if you're landing in spam or promotions.
Effective deliverability monitoring requires a seed list of inboxes across major providers (Google, Microsoft) to simulate real-world placement.
Run placement tests before launching a new campaign and weekly thereafter. This helps you isolate issues caused by new copy, domains, or volume.
At scale, manual spot-checks fail. Automated placement testing is the only way to monitor 50+ domains and catch reputation dips.
Placement testing helps diagnose if issues are domain-specific (one domain hits spam) or content-specific (all domains hit spam with new copy).
Placement testing isn't a one-time check you run before a campaign. For teams sending at scale, it's a continuous monitoring process—a feedback loop for your entire outbound infrastructure.
Without it, you're flying blind. You burn through domains, waste money on leads that never see your message, and can't diagnose why your reply rates suddenly dropped to zero.
When you manage dozens of domains sending thousands of emails daily, you can't rely on open rates to measure success. The real problems are invisible until it's too late.
For a Deliverability Lead or RevOps leader, an effective placement testing system provides confidence and control over the outbound function. The ideal state isn't about hitting 100% inboxing; it's about having a predictable, measurable system.
Setting up a deliverability monitoring system is an infrastructure project, not a campaign tactic. It requires a systematic approach.
Manually managing a seed list and testing workflow is feasible for one person sending 1,000 emails a month. It breaks completely when you have a team managing 50+ domains sending 100k+ emails. This is where an infrastructure platform becomes non-negotiable.
Look for core functionality that handles:
SuperSend is designed as this execution and infrastructure layer for outbound teams sending at volume. It integrates placement testing directly into the sending workflow, providing the visibility needed to scale safely. Before trying to implement this manually, it's critical to understand the core infrastructure strategies that support deliverability at scale.
