New features, improvements, and fixes shipped to FlushIt.
FlushIt is live. Send bulk email and SMS campaigns anonymously with crypto payments. No KYC, no identity verification, no approval process. Register with just an email and password, buy credits with cryptocurrency, and start sending immediately.
Pay for credits with Bitcoin (BTC), Ethereum (ETH), BNB, Solana (SOL), USDT (ERC-20), USDT (TRC-20), USDT (BEP-20), USDC (ERC-20), and USDC (SOL). Payments are verified directly on-chain with no intermediaries.
Credits are now reserved atomically before sending begins. If a send fails, credits are automatically refunded. Double-spending and race conditions are eliminated with database-level locking.
Track email opens and link clicks in real-time. Each campaign now shows per-recipient delivery status, open timestamps, and click-through data. Tracking is optional and can be disabled per campaign.
Test different subject lines or email content with a subset of your recipients. Set sample size, choose winner criteria (opens or clicks), and automatically send the winning variant to the remaining audience.
Invite team members to your account with role-based permissions. Owners, admins, members, and viewers each have scoped access. Team members share the account credit balance.
Receive real-time HTTP notifications for delivery events. Configure endpoints for sent, bounced, failed, and campaign completed events. All payloads are signed with HMAC-SHA256 for authenticity verification.
Generate professional email templates with AI. Describe your email in plain language and get production-ready HTML. Edit the generated output before saving. Powered by large language models.
Verify custom sending domains with DNS TXT records and configure DKIM signing for improved deliverability. Domain verification now includes automated DNS checks and status monitoring.
Per-user and per-IP rate limiting across all API endpoints. Configurable sending rate limits protect sender reputation and prevent accidental bursts. Automatic throttling for high-volume campaigns.
