Domain protection

Your main domain never sendsand every limit is published

A burned domain is the fear behind most cold email. Here is what Outlevo does about it, with the numbers it actually uses, read from the code that runs.

Which domain sends

Lookalike domains, never your own

Outlevo sends only from lookalike domains it proposes (for example getacme.com or tryacme.com), never from your main domain.

  • An owner or admin picks the domains and the sender names, and a domain is bought only after they confirm
  • Each sending domain has at most 5 mailboxes
  • SPF, DKIM and DMARC are set up and checked before a domain is marked ready
  • acme.comyour main domain: sends nothing
  • getacme.comproposed sending domain
  • tryacme.comproposed sending domain
  • acmehq.comproposed sending domain

Warm-up and daily limits

A new mailbox earns its place before it sends to anyone.

  1. 1

    Warm-up

    A new mailbox sends nothing until it is warm: at least 14 days, usually about 3 weeks.

  2. 2

    The bar to start

    A mailbox counts as warm at a warm-up reputation of 95% after at least 14 days, or after 21 days when no reputation score is reported.

  3. 3

    If it never gets there

    A mailbox that has not reached 95% in 35 days is stopped.

  4. 4

    A daily limit

    It sends at most 30 a day from each mailbox Outlevo runs.

When Outlevo pauses sending

Outlevo watches every campaign and every mailbox. These are the thresholds.

Campaigns and mailboxes

Each campaign and mailbox is judged on its last 200 sends, once it has 50: above 3% hard bounces or 5% unsubscribes, it pauses. One spam complaint pauses the campaign, two pause the mailbox.

Blocklists

Every sending domain is checked daily against Spamhaus and SURBL. A listed domain has its mailboxes switched off and its campaigns paused until it is delisted. A lookup the blocklists do not answer counts as unknown, never as listed.

After a pause

You are told why, and a person decides

You are told each time, with the reason and what to check. Only an owner or admin restarts a switched-off mailbox, and a person starts the campaign again. Outlevo never restarts on its own.

  • The campaign page says why, for example "Paused to protect your domain: 4.1% hard bounces in the last 120 sends"
  • Every pause is written to the audit log
  • Campaignpaused: 4.1% hard bounces in the last 120 sends
  • Mailboxswitched off until an owner or admin releases it
  • Domainlisted: mailboxes off until it is delisted

Who is emailed

Only verified addresses, never your customers

Most bounces and complaints are decided before the email is written, by who is on the list.

  • An email goes only to an address verified valid in the last 30 days
  • Catch-all domains, where an address cannot be confirmed, are skipped, and each skipped lead says why
  • Existing customers and companies with an open deal are left out of the accounts Outlevo works on
  • Anyone who unsubscribed or asked not to be contacted is suppressed before every send
  • The first 10 emails of every campaign wait for you to approve, edit or remove each one
  • Verified in the last 30 dayssent
  • Catch-all domainskipped, with the reason
  • Customer or open dealnever contacted
  • Unsubscribednever again

Questions about domain protection

Can Outlevo promise my domain will never be blocklisted?
No tool can promise that a domain will never be blocklisted. These rules make it unlikely and stop a problem early instead of letting it grow.
What if I send from my own mailboxes?
On Growth you can send from your own mailboxes instead; the same limits and pauses apply to them. Then the domain is the one you chose, so keep your main domain out of it.
Who can start sending again after a pause?
Only a person. Only an owner or admin restarts a switched-off mailbox, and a person starts the campaign again. Outlevo never restarts on its own.
