Sending safety
The failure modes most tools do not talk about.
Deliverability marketing stops at warm-up and spam scores. These decide whether a bad afternoon becomes an apology email to your whole list.
Send idempotency
A retry cannot produce a duplicate send. The same step to the same person sends once, even if the job runs twice.
Opt-out enforced before enrolment
Suppression is checked when someone enters a sequence, not just before each send — so an unsubscribed contact never enters at all.
Staggered sending
Sends are spread rather than fired in a block, which is what mailbox providers expect from a human sender.
Interrupted sends are flagged
If a run is interrupted it is surfaced for review rather than silently re-sent, because silent recovery is how people get mailed twice.
If you have been burned by a sequencer before, these four lines are probably the most useful thing on this page.
Measured, not assumed
Placement per mailbox, not per account.
Reputation is earned by the sending domain, so it is measured that way.
Inbox placement
Measured per mailbox, across the last 30 days
Placement is measured per mailbox rather than as an account average, because reputation is earned by the sending domain — one bad mailbox does not have to drag the rest down.
Reply rate by send window
Indexed, illustrative — your own data replaces this
Send-time optimisation is worth roughly what the data behind it is worth. Measured on your own mailboxes and your own market, not an industry average borrowed from someone else.

your domain only
Deliverability is not a setting. It is a discipline.
Domains rarely die from one bad campaign. They die from a hundred small mistakes nobody was watching for. Quotarider watches, and refuses to send when the odds are against you.
Run the full domain check before you send anything
Enter your sending domain and Quotarider validates SPF, DKIM, DMARC, MX and reverse DNS live, scores the result out of 100, and gives you the exact record to paste if something is missing.
- SPF, DKIM, DMARC, MX and rDNS validated live
- A score out of 100 with the specific gaps named
- Copy-paste DNS records for whatever is missing
- Re-runnable any time your DNS changes
Per-mailbox health, watched every day
Each connected mailbox carries a health score built from bounce rate, complaint signals, send velocity and reply ratio. When one starts to slip, Quotarider throttles it before the damage spreads to the domain.
- Bounce and complaint tracking per mailbox
- Automatic throttling when health drops
- Warm-up ramp for new mailboxes
- Hard bounces auto-added to suppression
Agents keep your list clean.
Reply Triage detects unsubscribe intent even when someone just writes "take me off this" — and adds them to suppression before your next send turns into a complaint.
Straight answers.
What does the deliverability checker test?
SPF, DKIM, DMARC, MX and reverse DNS for your sending domain, scored out of 100 with the missing records shown as copy-paste values.
Will Quotarider stop a risky campaign?
Yes. Inbox Shield blocks the launch and lists the specific problems — failed authentication, spam-trigger copy or send velocity that is too aggressive.
Do you handle unsubscribes automatically?
Yes. Unsubscribes, hard bounces and complaint signals are added to your suppression list and enforced at send time.
Do you warm up new mailboxes?
Yes, new mailboxes ramp gradually with daily caps rather than sending at full volume immediately.
Ask for it. Vera does it.
