Your email should land in the inbox, not the spam folder.
Most small-business email fails quietly: it's sent from a shared address, with no authentication, to a list that was never cleaned. Twinvia fixes all three without you learning a single acronym.
Your own sending domain
Marketing goes out as [email protected], from your domain, never from a shared one. We walk you through two DNS records and verify them.
Automatic warm-up
A new domain that sends 10,000 emails on day one gets blocked. Twinvia ramps your volume over two weeks so mailbox providers learn to trust you.
Score before you send
Every campaign gets a plain-English inbox score covering authentication, complaint rate, list health and spam triggers. Fix what's red, then send.
Watched after you send
Complaints, bounces and blocks are tracked daily. If the complaint rate approaches the limit Gmail enforces, sending pauses before your reputation is damaged.
One sentence, not a report.
Deliverability tools made for big companies show you forty metrics. Twinvia shows you a score and the one thing to change. Most of the time, there's nothing to change.
Behind the score: the same authentication Gmail and Yahoo now require from every bulk sender, one-click unsubscribe headers, bounce handling, and a suppression list that follows every contact who leaves.
What the big providers require in 2026
Gmail, Yahoo and Microsoft now block bulk senders who miss any of these. Twinvia handles every line.
