FAQsGot Questions? We Have Answers.
Everything you need to know before getting started — plans, billing, AI features, and more.
How does the 7-day free trial work?
Sign up in 30 seconds — no credit card required. You get full access to ColdBox for 7 days with 1,000 emails, 500 contacts, and 1 email account. Most users see their first replies within the trial period. When it ends, just pick a plan to keep going.
Can I switch plans at any time?
Absolutely. Upgrade anytime and get instant access to higher limits — no waiting. Downgrade whenever you want, and the change kicks in at your next billing cycle. There are no lock-in contracts and no cancellation fees, ever.
What counts as a 'monthly email'?
Each outreach email and follow-up sent from your connected accounts counts toward your limit. Warmup emails do not count — they are free and unlimited on every plan. This means 100% of your quota goes toward reaching real prospects.
How do AI Reply Agents work?
AI Reply Agents read every incoming response, handle objections, answer questions, and book meetings on your calendar — automatically. On Starter you get 1 agent handling 50 replies/month. Growth gives you 3 agents with 500 replies/month. Max unlocks unlimited agents and replies. It is like hiring a tireless SDR that works 24/7. Start your free trial to see them in action.
What's the difference between standard and premium warmup?
Standard warmup (included free on all plans) gradually ramps your sending to 50 emails/day using human-like engagement patterns. Premium warmup (Max plan) scales up to 200/day using priority inbox provider networks, building sender reputation 4x faster. Both help you maintain 95%+ inbox placement.
Do yearly plans really save 15%?
Yes — and it adds up fast. For example, the Growth plan drops from $85/month to just $72.25/month ($867/year instead of $1,020). That is $153 back in your pocket every year. The discount applies to all paid plans and add-on packages. You can start monthly and switch to annual anytime.
What are AI Credit packages for?
AI Credits power premium features like the AI Sales Agent, AI Autopilot, and AI-generated sequences. They are optional add-ons on top of the AI Reply Agents included in your plan. Starting at just $9/month for 500 credits ($0.018 per personalized email), they are one of the highest-ROI investments you can make in your outreach.
Can I connect unlimited email accounts?
Yes, all paid plans (Starter, Growth, and Max) include unlimited email account connections at no extra cost. Each account gets its own warmup and reputation management. More accounts means you can distribute sending volume for even better deliverability.
What payment methods do you accept?
We accept all major credit and debit cards via Stripe, plus PayPal and regional payment methods. Enterprise customers can arrange custom invoicing. All payments are processed securely with full PCI-DSS compliance. Start your free trial now — you will not be charged until you choose a plan.
Is there a refund policy?
Yes. We offer a 14-day satisfaction guarantee on all paid plans. If ColdBox is not the right fit, contact our support team for a full refund — no questions asked. Between the 7-day free trial and the 14-day guarantee, you have 21 days to decide completely risk-free.
