How do rolling 30-day allowances work?
Your plan quota allows sending up to your limit within any rolling 30-day window. You don't have to wait for arbitrary calendar month boundaries — your capacity dynamically replenishes as older sends age past 30 days.
Can I upgrade or switch plans at any time?
Yes. Upgrades take effect immediately. You can upgrade using existing account balance or by completing checkout via PayPal, Card, or cryptocurrency. Your sending limit and sender identity allowance will expand instantaneously.
Why is there a 3-minute cooldown between campaign runs?
To safeguard sender domain reputation and protect against mailbox provider throttling (Spamhaus, Google, Microsoft), dispatches require a 3-minute interval between runs to optimize long-term inbox placement.
What is the free email provider rule on Free and Growth plans?
Free and Growth tiers exclusively support custom business domains. Free webmail providers (such as @gmail.com, @yahoo.com, and @outlook.com) are automatically removed during import. To import and send to all email providers without domain restrictions, upgrade to Pro or Agency.
How does cryptocurrency deposit work?
Select 'Pay with Cryptocurrency' in the checkout modal. You'll receive a secure cryptocurrency invoice supporting over 150 crypto assets (Bitcoin, Ethereum, USDT, LTC, and more). Once blockchain confirmations occur, your workspace balance or plan is credited automatically via instant IPN webhooks.
Why are there daily sending limits on Free and Growth tiers?
Daily sending caps are an industry-standard mechanism to prevent sudden volume spikes that could damage sender domain reputation. Pro and Agency tiers unlock unlimited daily dispatches with high-reputation routing.
Are there any setup fees or hidden sender verification delays?
Zero setup fees and zero verification delays. You can register sender identities in your workspace and start dispatching cold outreach campaigns immediately without waiting days for manual approval.
