Hi Marcus,

Congrats on the Series B raise — saw the TechCrunch piece last week. With the EMEA expansion ahead, I imagine scaling your outbound team without losing message quality is top of mind.

We helped CloudSync (similar stage, same ICP) 4x their pipeline in 60 days with AI agents that write every email from scratch. Worth a 15-min look?

FAQ

Frequently Asked Questions About AI Cold Email

Everything you need to know about AI email outreach automation and Sellinger's AI email agent.

How do you write cold emails that get replies?
Cold emails that get replies share three traits: deep personalization (referencing real prospect context, not just a first name), a clear value proposition relevant to the recipient's role, and brevity (under 100 words). AI cold email tools like Sellinger automate this by researching each prospect's company news, LinkedIn activity, and tech stack before writing a unique email, achieving 12%+ reply rates at scale.
What is the average cold email reply rate?
The average cold email reply rate across the industry is 2-5.8%. Top performers using AI-personalized outreach achieve 10%+ reply rates. Sellinger's AI email agent averages 12% reply rates by writing every email from scratch based on deep prospect research, with no templates or generic merge tags. The key difference is genuine personalization vs. mass-blasted templates.
What is email sequencing and how does AI improve it?
Email sequencing is a series of automated follow-up emails sent to prospects over time. Traditional sequences use static templates with fixed timing. AI-powered email sequences adapt dynamically: the AI reads replies, adjusts follow-up content based on engagement signals, handles objections, and stops the sequence when a meeting is booked or the prospect opts out. Sellinger's AI email agent manages the entire sequence autonomously.
What is an AI email agent?
An AI email agent is an autonomous software agent that handles the entire cold email workflow: researching prospects, writing personalized emails, managing follow-up sequences, and handling replies. Unlike traditional email tools that use templates with merge fields, an AI agent writes every email from scratch based on deep prospect research.
How does Sellinger personalize cold emails?
Sellinger researches each prospect individually before writing. It analyzes their LinkedIn profile, company news, tech stack, recent funding, job changes, and mutual connections. This research is woven naturally into every email, making each message genuinely relevant, not just a template with a first name inserted.
What email providers does Sellinger work with?
Sellinger supports Gmail, Google Workspace, Outlook, Microsoft 365, and any custom SMTP/IMAP setup. You can connect multiple accounts and the agent automatically distributes sends across them for optimal deliverability and volume.
How does email warmup work?
When you connect a new email account, Sellinger gradually increases sending volume over 2-4 weeks, exchanging realistic emails with our warm-up network. This builds sender reputation with email providers so your real outreach lands in the primary inbox, not spam or promotions.
Can I connect multiple email accounts?
Yes. Most teams connect 5-20 email accounts per campaign. Sellinger rotates sending across all connected accounts automatically, respecting per-account daily limits and warmup status. This maximizes total sending volume while protecting each account's reputation.
What's the difference between Sellinger and Instantly?
Instantly is a sending tool that automates template-based sequences with variables. Sellinger's AI actually writes each email from scratch after researching the prospect. It also handles full conversations: reading replies, answering questions, handling objections, and booking meetings, not just initial outreach. Think of it as having a full-time SDR vs. a mail merge tool.
How does Sellinger handle email replies?
The AI reads every incoming reply with genuine comprehension. It categorizes responses (interested, objection, question, out-of-office, unsubscribe), then responds appropriately: answering questions, addressing objections with relevant case studies, or sending a booking link. Complex edge cases are flagged for human review.
What sending limits does Sellinger use?
Sellinger uses conservative, provider-aware limits: typically 30-50 emails per day per account for new domains, scaling up to 100-150 as reputation builds. Sending is spread naturally throughout business hours with randomized delays to mimic human patterns.
Can I review emails before they're sent?
Absolutely. You can enable approval mode where every email is queued for your review before sending. Most teams start with approval mode on, then switch to autonomous sending once they're confident in the agent's output quality, usually within the first week.
How does Sellinger maintain high deliverability?
Multiple layers: automated warm-up for new accounts, DKIM/SPF/DMARC verification, real-time bounce handling, spam complaint monitoring, blacklist checks, smart sending patterns, and content analysis that avoids spam trigger words. Our average inbox placement rate is 99.2%.
