Myth: Plain text emails always have better deliverability than HTML. True or False?
False. Plain text emails do not always have better deliverability than HTML. Both formats deliver successfully from authenticated, reputable senders. Format choice should match content needs and audience expectations.
HTML enables richer content, tracking, and branding that many programs require. Well structured HTML causes no deliverability problems. Malformed HTML might trigger issues, but the solution is better HTML, not format avoidance.
Some specific situations favor plain text (personal outreach, certain B2B contexts), but this reflects audience preference and appropriateness rather than inherent deliverability advantage.
