Kill HubSpot Sequences

Replace HubSpot Sequences with Claude, n8n (self-hosted), and Postmark

$90/seat/mo

HubSpot locks email sequences behind Sales Hub Professional at $90/seat/month. Three reps doing outreach: $270/month. n8n handles the sequencing logic, Postmark handles delivery and reply detection. Your sequences run on Railway for about $20/month total, regardless of how many reps use them.

Why Replace HubSpot Sequences?

  • ×Sales Hub Professional costs $90/seat/month - three reps is $270/month, five reps is $450/month, all on an annual contract
  • ×Sequences are explicitly excluded from Starter ($20/seat) - you can't buy them separately, you must upgrade the entire seat
  • ×Mandatory $1,500 onboarding fee before you've enrolled a single contact
  • ×n8n + Postmark replaces the sequence engine for ~$20/month total with no per-seat fees

What People Use HubSpot Sequences For

Multi-step email sequences with day-based delays
Automatic unenrollment when a contact replies or books a meeting
Task reminders between email steps (call, LinkedIn outreach)
Personalized 1:1 sales outreach at moderate volume
Sequence performance tracking (open rate, reply rate)

Kill Checklist

Railway hosts n8n (Hobby plan, $5/month). Postmark handles email delivery and reply detection. Sign up for both. In Postmark, verify your sending domain by adding SPF and DKIM DNS records.

2

Deploy n8n on Railway

~5 mins

Use the one-click template (4,908 total projects, 3,855 active, 100% deployment success rate). If you already deployed n8n from the Kill HubSpot Workflows guide, skip this step - use your existing instance.

3

Set up Postmark inbound for reply detection

~15 mins

In Postmark, set up an inbound domain (e.g. reply.yourdomain.com). Add a DNS MX record pointing to inbound.postmarkapp.com. Set the inbound webhook URL to your n8n instance + /webhook/postmark-inbound. In sequence emails, set Reply-To to your inbound domain so replies route through Postmark.
