Free Email List Cleaner – Improve Email Deliverability and Campaign Performance

Hacker News - Fri, 03/13/2026 - 4:25pm

Email marketing remains one of the most effective ways to connect with customers and grow a business. However, many campaigns fail because businesses send emails to outdated or inactive addresses. This is why using a free email list cleaner is essential for maintaining a healthy email marketing strategy.

A free email list cleaner helps remove invalid, duplicate, and inactive email addresses from your contact list. By cleaning your list regularly, you can improve email deliverability, reduce bounce rates, and ensure your messages reach real users instead of spam folders.

Many marketers build large email databases over time, but without proper maintenance these lists can quickly become ineffective. With the help of a free email list cleaner, businesses can filter out low-quality contacts and focus on sending campaigns to active subscribers who are more likely to engage.

For example, tools like the Email List Cleaner Tool can help users quickly analyze and clean their email databases before starting outreach campaigns.

Businesses that want better results from their email marketing should regularly clean and optimize their contact lists. Platforms that provide email extraction, spam testing, and list cleaning tools make this process easier and more efficient.

Wan 2.7 planned for March release with big upgrades

Hacker News - Fri, 03/13/2026 - 2:30pm

Wan 2.7 is planned for release in March and appears to be a broad upgrade over Wan 2.6.

According to the current roadmap, improvements are expected in:

visual quality audio motion dynamics stylization consistency Planned new capabilities include:

first-frame / last-frame guided video generation 9-grid image-to-video subject and voice reference instruction-based video editing video recreation / replication The overall direction seems to be a more complete video generation and editing workflow rather than a single-feature update.

Atlascloud.ai has been in contact with the Wan team and plans to support Wan 2.7 on launch day.

Would be interesting to see benchmark examples and workflow demos once it ships.

Show HN: Disposable inbox API with OTP extraction and WebSocket push

Hacker News - Fri, 03/13/2026 - 2:29pm

I built a REST + WebSocket API for programmatic disposable email inboxes.

The main use case I kept running into while building: automated testing of sign-up/verification flows. You need a real inbox, a real OTP, and you need it fast. Existing options were either not API-first, had terrible docs, or charged $50/mo before you could even try them.

What it does: - POST /v1/inboxes to register an inbox - GET /v1/inboxes/:inbox/otp to pull the latest OTP (parsed automatically) - WebSocket connection for real-time push instead of polling - Attachments, custom domains on higher tiers

Auth is SHA-256 hashed API keys, usage tracked per-user (not per-key, so rotating keys doesn't reset your quota). Rate limit headers on every response.

Free tier: 5k req/mo, no credit card.

Interactive playground: https://www.freecustom.email/api/playground Docs: https://freecustom.email/api/docs

Happy to answer questions about the architecture — running on Node/Express, Redis for rate limiting and pub/sub, MongoDB for storage.
