Mailboxes fail quietly and volume falls with them
Mailboxes drop off the sequencer
Microsoft asks for reconnects roughly every 90 days, and each one is found when a campaign stalls.
A burned mailbox leaves a hole
Its share of the daily send stops. Replacing it means new domains and another warm-up period.
Setup is manual, mailbox by mailbox
Tenants, DNS, mailboxes and the sequencer connection, all done by hand.
How sending.ac keeps mailboxes sending
Configured and isolated before the first send
Every domain gets its own tenant, with SPF, DKIM and DMARC verified before any mailbox sends. Pre-warming is a toggle on any plan.
- Up to 75 mailboxes per domain on Azure
- Up to 10 per domain on Google
- Any TLD
From domain to sending mailbox
- Domain addedBought through sending.ac on any TLD, or imported
- Tenant createdOwn IPs, own reputation, own admin panel
- DNS verifiedSPF, DKIM and DMARC checked before the first send
- Mailboxes connectedPre-warmed if you toggled it, paired with your sequencer
Reconnects and replacements without a ticket
A mailbox that disconnects reconnects automatically. When one burns, a replacement takes its place and the daily send stays level.
- Automatic reconnects on every mailbox
- Replacements slot into the same rotation
