Emailable

Emailable is a dedicated email verification tool designed to help you maintain a healthy sender reputation. You can upload your existing contact lists to identify undeliverable addresses, spam traps, and syntax errors before you hit send. By cleaning your lists, you reduce bounce rates and ensure your messages actually reach your customers' inboxes rather than the spam folder.

The platform offers both bulk list cleaning and a real-time API to verify emails at the point of entry on your website. You can integrate it directly with your favorite email service providers to automate the cleaning process. It serves businesses of all sizes, from individual creators to large enterprises, providing detailed reports on why specific addresses were flagged as risky or invalid.

Email on Acid

Email on Acid helps you eliminate the guesswork of email marketing by previewing your campaigns across over 100 different email clients and devices. You can catch rendering issues, broken links, and accessibility problems before you hit send, ensuring every subscriber has a consistent experience. The platform automates the tedious manual testing process, allowing your team to deploy high-quality emails faster and with more confidence.

Beyond simple previews, you can optimize your inbox placement with deliverability tools that check your IP against blacklists and validate your SPF and DKIM records. Whether you are a solo developer or part of a large enterprise marketing team, the platform provides the technical insights needed to bypass spam filters and improve engagement. You can integrate these checks directly into your existing workflow to maintain brand standards across every communication.
