Industry definitions for email at scale

Reputation Hot-Swap

A live system that continuously monitors reputation signals and automatically replaces degraded sending and landing infrastructure mid-campaign-so sending continues without stopping, resetting, or re-warming.

• What it prevents: deliverability collapse, campaign pauses, tracking resets, broken UX.
• What makes it unique: the swap happens before inbox placement drops, not after damage.

Sender Continuity

Keeping every recipient tied to a consistent sender identity across a multi-step sequence-so the story is coherent and trust can build. HotSwap Mail binds each recipient to a specific mailbox so subsequent emails arrive from the same sender instead of random mailboxes/domains.

• Why it matters: multi-step campaigns break when each step appears to come from a different person/company.
• Outcome: higher comprehension, higher trust, fewer “who are you?” replies.

Recipient-Domain Cadence Control

Managing sending pace and distribution with the recipient’s email provider in mind (e.g., Gmail, Yahoo, Microsoft), because different providers respond differently to volume patterns from a given sender.

• Why it matters: volume sensitivity can trigger filtering even when your copy is fine.
• What it does: spreads sends safely across recipient domains to reduce spam/promotions triggers.

Inbox Placement

Where emails land inside the recipient’s mailbox experience (Primary inbox vs Promotions vs Spam). Inbox placement is the practical outcome that determines whether campaigns work.

• Spam avoidance: staying out of Junk/Spam folders.
• Primary placement: improving the chance of landing in Primary instead of Promotions (especially in Gmail).

Deliverability

The probability that an email reaches the recipient’s mailbox ecosystem successfully and is accepted by filters-often confused with opens or replies. With HotSwap Mail, exceptional deliverability is the result of continuous reputation protection and cadence control.

Gmail Promotions Tab

A Gmail category that groups promotional emails. Avoiding Promotions is not purely a copy trick-provider signals, reputation, cadence, and consistency often play a decisive role at scale.

• What we do: protect reputation continuously, manage cadence, and support preview text to improve placement patterns.
• Reality check: placement varies by list quality, recipient behavior, and content.

First-Party Links (No Cloaking / No Forwarders)

Using direct links on first-party domains rather than cloakers/forwarders. HotSwap Mail keeps landing pages integrated with sending and monitors landing-domain health-so links remain stable and reputation can be managed end-to-end.

Downtime

Any pause, reset, or forced re-warm that interrupts a live sending program. At scale, downtime compounds into missed deadlines, broken sequences, lost momentum, and inconsistent measurement.
