Event promotion lives on a clock. Flash sales have a 48-hour window; webinar registrations drop when invites go out late; conference invitations need to land months in advance while sponsor outreach runs in parallel. And every one of those runs on cold email — powered by a fragmented tool stack where infrastructure setup takes longer than the event promotion itself.
ColdSend is a cold email sequencer and the infrastructure it sends from, built together in one platform. ColdSend is built on a very strong email marketing foundation — the underlying infrastructure was custom-built for email marketing, and that's what makes the cold email use case accessible in the first place. Creating domains and mailboxes inside email marketing systems is usually a lot of pain, so we made that part easy: connect a domain, create up to 100 mailboxes on it, and start building campaigns.
The Tool Chaos
- Promoting with a fragmented stack means setup takes longer than the event itself
- Flash-sale windows close while you configure DNS, mailboxes, and vendor accounts
- Mailboxes billed per seat, so every launch wave you scale adds to the bill
- When deliverability drops mid-promotion, the sequencer blames the infra and the infra blames the sequencer
One Platform, One Price
- Sequencer + infrastructure, together. Conference invitations, sponsor pitches, webinar reminders — parallel campaigns from one dashboard, no vendor hopping, no finger-pointing between tools.
- Built on a strong email marketing foundation. The underlying infrastructure was custom-built for email marketing, where domain and mailbox creation is usually a chore. We made that part easy: connect your domain, and we handle SPF, DKIM, and DMARC. Then create up to 100 mailboxes on it — no per-mailbox fees.
- Pricing that scales with domains, not seats. Start at $99/mo with one domain. Every extra domain is $30/mo and adds 100 mailboxes and 25,000 monthly sends — separate domains for promotions vs sponsors vs partner comms if you like.
- IPs that self-manage. The infrastructure rotates IPs and swaps flagged ones automatically. No migration, no downtime — your event pushes stay out of spam folders without you babysitting reputation.
- Bring your own inboxes too. Import existing Google, Outlook, or SMTP inboxes onto any plan — no extra charges or sending limits on infra you bring.
Built for Events
- Conference invitations. Multi-wave sequences — save-the-date, early bird, final reminder — managed as one workflow.
- Sponsor outreach. Conveyor-belt sponsor prospecting on dedicated domains instead of your personal emails.
- Webinar promotions. Tight-loop reminder sequences built for volume spikes.
- Product launches. Coordinated announcement + follow-up waves synchronized with your launch calendar.
Getting Started
- Sign up at $99/mo — connect your first domain and create up to 100 mailboxes.
- Import your list, build reminder sequences, and send the first wave.
- Add event-specific domains at $30/mo each as calendar density grows (up to 20).
