Why Mail Maya Uses Text-Only Emails

The deliverability science behind plain text cold email.

Mail Maya sends all emails in plain text — no HTML formatting, no images, no buttons, no tracking pixels. This is not a limitation. It is a deliberate design decision that significantly improves your inbox placement.

Why HTML hurts deliverability

• HTML emails have a much higher spam score than plain text emails
• Tracking pixels are a signal used by spam filters to classify marketing email
• Emails with images and formatting look like bulk newsletters — spam filters treat them accordingly
• Cold email should look like a personal email — HTML makes that impossible

What you lose (and why it does not matter)

You lose the ability to add logos, buttons, and formatted layouts. For cold outreach, this is actually a positive. The goal of a cold email is to start a conversation — not to run a branded marketing campaign. A simple, readable plain text email converts better because it feels personal.

Other deliverability features Mail Maya includes

• Random delay between emails to mimic human sending behaviour
• Message-ID variation to avoid fingerprinting by spam filters
• X-Mailer header randomisation
• Zero-width character insertion for content fingerprint resistance
• Sender name in the From header (e.g. 'Jane Doe <jane@company.com>')

Tip: The single biggest thing you can do for deliverability is to write emails that sound genuinely personal and relevant to the recipient. No technical trick replaces quality copy.
