This policy applies to every workspace and every mailbox sent through Sendqube, whether connected via Microsoft 365, Gmail, or SMTP. It exists to keep deliverability high for every sender on the platform — spam complaints against one workspace can affect what inbox providers think of Sendqube as a whole.
You may only email contacts you have a legitimate basis to contact. You agree not to:
Every contact added to Sendqube — by CSV import, manual entry, or Lead Finder — requires you to explicitly confirm that the contact has consented to receiving commercial email from you, or that you have an existing business relationship or other lawful basis to contact them. This confirmation is recorded with a timestamp on the contact record. Sendqube has no way to verify the truth of that confirmation — you are solely responsible for having a lawful basis to email every contact you add.
Every connected mailbox has a daily send limit, and campaigns pace sends across working hours and sending days rather than firing all at once. When a sequence has multiple mailboxes assigned, sends rotate across them automatically, weighted toward whichever mailbox has the most daily volume left.
Sequences can also be started on a gradual ramp-up instead of full volume immediately — recommended for new or recently-paused sequences to protect mailbox reputation.
New mailboxes can be enrolled in automatic warmup, which exchanges real engagement with other Sendqube senders and gradually ramps daily volume before the mailbox is used for full-scale outreach. We strongly recommend warming up any mailbox that's new or hasn't sent outbound email before.
Hard bounces are caught immediately at send time, and delayed bounces are detected automatically afterward — both are tracked per mailbox so you can see reputation risk before it grows. Reply detection can automatically pause outreach to a contact once they respond, so no one gets chased after replying. Consistently high bounce or complaint rates on a mailbox may result in that mailbox — or in serious or repeated cases, the workspace — being paused while we look into it.
Every campaign includes an unsubscribe link. Once a contact unsubscribes, it's honored workspace-wide — not just for the sequence they unsubscribed from — and they won't be re-enrolled by that workspace again.
Verification credits let you check an address before sending to it, reducing bounce rates before they happen. We recommend verifying any list you didn't collect through a direct opt-in on your own site or product.
Violating this policy can result in a warning, a mailbox or workspace being paused, or account termination for serious or repeated violations, at our discretion. We'll always try to reach you first unless the activity poses an immediate risk to deliverability for other senders on the platform.
If you receive spam that appears to have been sent through Sendqube, forward it with full headers to dev@sendqube.in and we'll investigate.
