Promo codes can stack on top of the 55% annual price (a 10% off code makes the total ~59.5% off list). LinkedIn seats are $15/seat/month, or $120/seat/year (33% off) on annual billing; seats added before July 6, 2026 keep the rate they were created at — existing customers are never moved to the new price.

Yes, you can upgrade at any time. We simply charge the difference between your current plan and the new tier.
Your emails will pause until the next month or you can upgrade to a higher tier for immediate access to more quota.
Cancel anytime from your Billing page — you keep full access until your billing period ends.
Yes — if you request it within 7 days of your payment and you haven't used the account to send. That means no campaign emails, no warmup emails, no LinkedIn or Instagram actions, and no lead or verification credits spent since that payment. Connecting a mailbox, importing contacts, and building a campaign without launching it don't count against you, so you can set everything up and still qualify. It applies to monthly, annual, and 3-year plans, and to your first payment as well as renewals. Email [email protected] from the address on the account. Lead credits and email verification credits aren't refundable to your payment method (unused credits never expire, and credits come back to your balance for anything we couldn't complete — an address we can't confirm is never charged), and LinkedIn or Instagram seats are refundable in the same window only if no account was ever connected to the seat.

The Business plan ($29.99/month) has been discontinued. WarmySender now offers three plans — Pro, Enterprise, and Ultimate. Customers already on the Business plan keep their plan, their pricing, and every feature exactly as before, including renewals — nothing changes for them. New customers choose Pro, Enterprise, or Ultimate; if you previously would have picked Business for more mailboxes or multiple workspaces, Enterprise is the next step up from Pro.
We support Gmail, Google Workspace, Outlook, Microsoft 365, and any custom SMTP server.
Sign up and choose a plan to get instant access. All plans include email warmup, campaigns, and the B2B lead database.
LinkedIn automation is available as a paid add-on at $15/seat/month on any plan. Connect your LinkedIn account and run multi-step campaigns with safety features built in.
Pro+ subscription plans include access to 200M+ verified B2B contacts across the US and Canada. Search by industry, location, company size, and more. Credits reset monthly.
Annual plans save 55% compared to monthly billing. The discount is evergreen, but framed with a real end-of-month deadline that resets monthly. The countdown you see on the pricing page resolves to the actual end of the current calendar month UTC — the urgency is real, but the 55% itself does not actually expire when the date hits. The framing rolls forward to the next month automatically.
Customers already on a previous annual rate keep their existing price. Your subscription continues to renew at the price you signed up for until you cancel or switch tiers. If you switch to a different annual tier (e.g. Pro Annual to Enterprise Annual), the new tier picks up the new 55% pricing automatically — you get the better deal on the new plan.
Yes. Any valid promo code can be applied at checkout on top of the 55% annual price. For example, a 10% off promo code on top of Pro Annual ($80.88/year) brings the total to roughly 59.5% off list price.
No. You get one free check a day with no account and no card. To check a whole list you can buy one-time verification credits from $79 for 100,000 — no plan and no recurring charge — and those credits never expire. Pro (300/mo), Enterprise (1,500/mo) and Ultimate (10,000/mo) each add a monthly verifier allowance on top, but a plan is one way in, not the only one.
No. One-time verification credits stay on your account until you use them — there's no monthly reset and nothing is lost if you don't finish a pack in one sitting. One credit is spent per confirmed result (valid, invalid, or risky), and a result we can't confirm is never charged. Credits are additive on top of any plan allowance rather than capped by it, and they skip the plan's gentle daily pace, so a pack can clear a big list the same day.
