Do plain text cold emails always inbox better?

Myth: False. Plain text cold emails do not always inbox better. Deliverability depends on **sender reputation**, authentication, and recipient relationship, not message format.

Plain text may feel more personal, which can improve engagement. But this is UX benefit, not filter benefit. Well formatted HTML from a good sender delivers fine.

Choose format based on brand and message needs. Plain text suits personal outreach feel. HTML suits branded communication. Neither inherently delivers better.
