1. Salesforge (Agent Frank)

Salesforge's Agent Frank is an SDR automation platform that combines deep personalization with reliable email deliverability, ensuring your messages stay out of spam folders. It brings lead generation and outreach together in one streamlined solution.

Multi-Channel Outreach

Agent Frank focuses on email and LinkedIn as its primary outreach channels, making it a dual-channel platform rather than spreading efforts across too many mediums. With support for over 20 languages, it’s well-equipped for global campaigns. While other tools may include SMS or phone integrations, Agent Frank prioritizes mastering these two key channels for B2B prospecting.

The platform synchronizes LinkedIn connection requests with follow-up emails, creating consistent messaging across both channels. This targeted approach helps ensure that prospects engage with cohesive and personalized communication.

Personalization Depth

Agent Frank takes personalization to a whole new level. Instead of relying on basic name placeholders, it pulls real-time data such as funding updates, hiring trends, tech stack details, and recent LinkedIn activity. This allows for messaging that feels relevant and informed.

Its personalization engine analyzes behavioral data, firmographics, and engagement patterns to identify high-intent prospects. It adapts its tone and messaging based on factors like company size, industry, and recent events, ensuring every outreach feels tailored. This level of precision significantly boosts engagement rates.

Deliverability Features

One of Agent Frank's standout features is its built-in Forge Stack, a deliverability toolkit integrated directly into the platform. It includes automatic email warm-up, account rotation, and advanced reputation management to tackle the common issue of emails landing in spam.

The Forge Stack also handles DKIM, SPF, and DMARC authentication automatically, while monitoring bounce rates and engagement metrics. By spreading email volume across multiple domains and IPs, it protects your sender reputation during large-scale campaigns. This eliminates the need for extra deliverability tools and integrates smoothly with CRM systems.

Integrations

Agent Frank works seamlessly with major CRM platforms, enabling automatic lead qualification and two-way data synchronization. It ensures all prospect interactions are recorded without manual effort.

The platform pulls CRM data, runs outreach campaigns, and updates lead statuses based on responses. This automation cuts down on time-consuming data entry and gives sales teams real-time insights into campaign performance.

Pricing

Salesforge uses a custom pricing model, so you’ll need to contact their sales team for a quote. Costs depend on factors like sending volume, features, and team size. While exact pricing isn’t shared publicly, Agent Frank is marketed as a more affordable alternative to hiring full-time SDRs, which typically cost $40,000 to $60,000 or more annually.

2. Artisan Ava

Building on Salesforge's commitment to precision and deliverability, Artisan Ava takes things a step further by offering autonomous, multi-channel engagement.

Pricing

While specifics aren’t publicly available, companies that have adopted AI SDR solutions like Ava have reported cutting costs by up to 70% compared to traditional outbound methods [5]. This cost efficiency is largely thanks to Ava’s ability to handle the workload of 5–10 human SDRs [5].

3. 11x.ai (Alice and Julian)

Alice focuses on securing qualified meetings through digital channels, while Julian manages phone calls, refining his techniques with every interaction [7].

Salesforge (Agent Frank) stands out for its automated outreach capabilities. It offers robust deliverability controls and advanced personalization tools, along with built-in warm-up sequences to safeguard sender reputation.

Artisan Ava supports email, LinkedIn, and phone outreach, leveraging AI-driven prospect research to create highly tailored messages for individual recipients. On the downside, it requires initial oversight to fine-tune its performance, and its integration options may not be as expansive as those of more established platforms.
