Frequently Asked Questions
Q: Are my email templates and lists secure?
Yes, all template design and processing happens locally in your browser. We never store or transmit your email copy, templates, or contact lists to any external servers.
Q: Will my generated HTML signatures work across all email clients?
Our signatures are built using standard nested HTML tables and inline CSS styles, which are compatible with major clients like Gmail, Outlook, Apple Mail, and Yahoo.
Q: How does the Spam Score Checker evaluate emails?
It analyzes the email content for spam trigger words, subject line length, excessive punctuation, uppercase text, and formatting patterns that trigger spam filters.
Q: Do DKIM, SPF, and DMARC generators make actual DNS changes?
No, they generate the TXT records you need to copy and paste into your domain registrar's DNS settings (e.g., GoDaddy, Cloudflare, Namecheap) to verify your domain.
Q: Can I import and edit existing HTML emails?
Yes, both the HTML Email Previewer and Email Template Builder allow you to paste or import custom HTML code, render it in real-time, and tweak inline CSS styling.
