Worth knowing

Gmail and Yahoo require bulk senders to authenticate with SPF, DKIM and DMARC, offer one-click unsubscribe and keep spam complaints under 0.3%.Source

Apple Mail accounts for about three quarters of tracked opens, and privacy protection affects roughly 55 to 60% of opens, so clicks are the better measure (Litmus, September 2026).Source

In Litmus's 2025 State of Email report, 35% of marketing leaders said email returns $10 to $36 for every $1 spent.Source

How it works

Questions about Email

Do you send the emails?

Your SMTP provider sends them, from your own domain. That keeps your reputation in your hands and the cost per email low.

Is open tracking accurate?

Opens are an estimate because Apple Mail Privacy Protection loads images automatically. Use clicks, replies and conversions for decisions.

What happens on a hard bounce?

The address is added to the suppression list and is never emailed again from that workspace.
