Overview
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.
ZeroBounce
ZeroBounce helps you protect your sender reputation by removing invalid, risky, and inactive email addresses from your marketing lists. You can upload your entire database for bulk cleaning or use the real-time API to verify emails the moment they are entered into your signup forms. This prevents bounces before they happen and keeps your data clean from the start.
Beyond simple verification, you can use the platform to test your email deliverability and monitor your blacklists. It identifies high-risk emails like spam traps and catch-all addresses that typical checkers might miss. Whether you are a solo marketer or part of a global enterprise, these tools help you increase open rates and maximize the ROI of your email campaigns.
