Envelope
The email envelope is everything someone sees about your email in their inbox before they open it. It includes the sender name, subject line, and preview text that guide their choice to open or ignore it.
The email envelope is the bit people see in their inbox before they open your message. It includes your sender name, subject line, and preview text. Think of it as the label on the outside of a package. It tells people what to expect in a quick glance.
It matters because almost every open starts with a snap decision. People scan their inbox, skim the envelopes, and choose what feels worth their time. A clear envelope can lift open rates, build trust, and keep you out of spam. A confusing envelope can train people to scroll past you.
Start by writing your email, then come back and shape the envelope. Use a sender name that feels familiar, a subject line that is specific, and preview text that adds one more reason to open. Test small changes over time and keep what performs best.
