A burned domain destroys company email for every department.
Company-wide deliverability collateral damage
When outbound triggers spam filters, transactional billing receipts and customer support tickets land in spam too.
Sudden unmonitored spam blacklisting
Spiking volume or hitting spam traps causes Google and Outlook to flag the entire corporate domain overnight.
High bounce rate penalties
Sending to unverified contact lists causes hard bounce rates to exceed 2%, triggering provider deliverability suspensions.
Single mailbox volume overload
Blasting 300 emails a day from a single rep mailbox violates provider acceptable use limits.
Missing technical authentication
Misconfigured SPF, DKIM, or DMARC records causes immediate gateway quarantines.

Frequently asked questions
Why is it dangerous to send cold emails from our primary company domain?
If outbound cold emails trigger spam complaints or high bounces, Google and Microsoft will penalize your entire domain. This causes customer support tickets, billing invoices, and executive emails to go straight to spam.
How does secondary domain rotation protect our brand?
SendroAI configures authenticated lookalike domains (e.g., getcompany.com instead of company.com) for outreach. If a secondary domain faces reputation issues, your core domain remains completely unaffected.
How many emails can each mailbox safely send per day?
We strictly recommend and enforce 30 to 45 emails per mailbox per day to remain well beneath provider anomaly detection limits.
Does SendroAI verify email addresses before sending?
Yes. Every contact record undergoes verification to ensure invalid addresses are purged before dispatch, keeping bounce rates under 1%.
What is included in the practical sending hygiene checklist?
The platform provides automated DNS checks (SPF, DKIM, DMARC), text-to-link ratio optimization, gradual ramp-up schedules, and automatic suppression of unsubscribed contacts.
