Delivery you can prove, so a “no” means no
Zero replies means nothing if the emails never arrived. Sellvance runs the domains, DNS and mailboxes, then checks where the mail lands, so a delivery failure shows up as its own result instead of as silence.
- ✓ One-click mailboxes on your own domains — no Google or Microsoft setup
- ✓ SPF, DKIM, DMARC and MX configured automatically
- ✓ A delivery verdict on every campaign
- MXVerified
- SPFVerified
- DKIMVerified
- DMARCVerified
Configured automatically — you never touch a DNS panel.
Why delivery decides whether an experiment counts
A reply rate mixes two things: whether the email arrived, and whether it persuaded. Sellvance separates them.
Authentication done right
We publish and verify the correct MX, SPF, DKIM and DMARC — no hand-edited TXT records, no SPF syntax roulette.
Placement tested on the real message
Send the actual rendered email to a test mailbox and see whether it lands in the inbox, in spam, or nowhere.
A delivery verdict from auto-replies
Mail providers hold back out-of-office replies for mail filed as spam. When they stop arriving, the Signal Check says delivery failed.
Replies blocked, not misread
While delivery fails, the reply rate isn't treated as a verdict on your audience, so you don't rewrite good copy for nothing.
Health checks before you send
Spam score, authentication results, blocklist status, and the sending IP with its reverse DNS and country, checked before they cost you an experiment.
Every reply collected
Replies are read over IMAP and forwarded wherever your team already works, so no answer goes uncounted.
Create a sending mailbox in one click
Pick a managed domain, choose a name, and Sellvance provisions a real, deliverable mailbox, with credentials configured and sending enabled. The first mailbox on a domain triggers full DNS setup automatically.
- ✓ Billed monthly in connects, or included in your plan
- ✓ Works alongside the mailboxes you already have
- ✓ Paused or overdue mailboxes are flagged clearly
Everything included, nothing to wire up
The work that normally takes days of DNS tickets, handled.

No credentials to manage
Mailbox usernames and passwords are generated and secured for you.
Rules that protect your domains
A burned domain costs you every experiment that runs on it. These checks can't be turned off, and each one exists to keep that from happening.
Authentication before the first send
A domain sends nothing until SPF, DKIM and DMARC are published and verified. Unauthenticated mail is what Gmail and Outlook reject first.
A daily cap on every mailbox
Each mailbox sends 30 emails a day by default and never more than 50. A steady, modest pace is what keeps a domain trusted.
Automatic pauses
When hard bounces or spam complaints rise past a safe level, the mailbox or campaign pauses and you see why. Fix the list, then resume.
Blocklist monitoring
Sending domains are checked against public blocklists. A listed domain pauses at once, before more mail adds to the damage.
Know the emails arrived before you judge the answer
Let Sellvance run the domains, DNS and mailboxes, and check delivery on every experiment.
