Unlimited core quotas

Mailboxes, leads, sends, and warmup are unlimited on-plan, with no counting seats or inboxes when you scale. Fair use protects platform quality for all customers.

Outbound in one workspace

Warmup, sending, Unibox, and analytics stay together so you are not duct-taping three vendors to run one campaign.

Cancel or switch cadence

Monthly plans stop cleanly. Annual plans are billed upfront; you can still move tiers when your pipeline changes.

Email outreach software FAQ

Answers for teams evaluating outreach platforms, warmup, and unified inboxes.

Email outreach software helps you send personalized messages to prospects at scale while managing deliverability, follow-ups, and replies. SignoFast connects your real inboxes (Google, Microsoft, or SMTP), warms them up, runs campaigns with sequences and variants, tracks performance, and routes every reply into one Unibox.
