Feature

v2.4.0

August 20, 2026

Multi-inbox rotation and warm-up intelligence

The platform now supports automatic rotation across multiple sending mailboxes within a single campaign, distributing send volume intelligently to protect deliverability. The inbox warm-up engine has been upgraded with adaptive throttling that adjusts daily send volume based on real-time inbox placement signals, reducing cold-start spam risk for new domains by an average of 60%.

Add up to 10 mailboxes per campaign on Growth and Scale plans with automatic round-robin rotation.
Warm-up engine now monitors inbox placement rates daily and adjusts ramp schedule automatically.
New Deliverability Dashboard shows domain reputation, bounce rates, and spam folder placement in real time.
Email health alerts sent to account admins when placement rates drop below configurable thresholds.

Improvement

v2.3.1

August 6, 2026

Personalization engine: industry-signal expansion and LinkedIn trigger coverage

The AI personalization engine has been updated with expanded coverage of industry-specific buying signals, including technology hiring spikes, funding round activity up to 30 days prior, and leadership changes detected from LinkedIn. Personalized first-line relevance scores have improved by 18% on internal benchmarks, and average open rates across test campaigns increased by 11 percentage points.

Funding round detection now covers Series A through Series E, with automatic persona-specific messaging variants.
Leadership change triggers (new VP of Sales, new CTO, etc.) added as a first-line personalization source.
Technology hiring signals now integrate with 14 additional job boards beyond LinkedIn.
Improved de-duplication logic prevents redundant personalization signals from stacking awkwardly.

Feature

v2.3.0

July 22, 2026

Clay integration and webhook-based custom data enrichment

SalesDeveloper now integrates natively with Clay, allowing customers to pipe enriched prospect records — built from any Clay table — directly into SalesDeveloper sequences. A new general-purpose webhook input lets advanced users push custom firmographic or behavioral data from any system into SalesDeveloper for use in personalization and ICP matching. This removes the previous requirement to use only SalesDeveloper's built-in data sources.

Native Clay integration: connect a Clay table, map columns to SalesDeveloper prospect fields, and sync on a schedule or trigger.
Inbound webhook endpoint accepts JSON prospect records from any external system.
Custom fields added to the prospect schema support up to 20 custom attributes per record.
Personalization engine can reference custom fields in message templates using a simple {{field_name}} syntax.
