Your AI email assistant

Describe the campaign in one sentence. AI returns a plan you can actually use: strategy, subject lines, preheader, the email, a call to action, personalization, A/B variations, follow-ups and deliverability suggestions.

Everything lands as an editable draft. Nothing is sent until you review it and press send — or until an automation you set up says so.

Generate campaign with AI How the AI works

Create a campaign for US dental clinics offering appointment scheduling software.

Example AI draft

Strategy: Lead with the cost of empty chairs from no-shows; offer a short demo to office managers, who own the schedule.
Subject lines: Fewer no-shows next month, {{first_name|there}}?Online booking your front desk will actually like
Preheader: Patients book, reschedule and get reminders — without phone tag.
Call to action: Book a 15-minute demo
Variation B: Angle: time saved at the front desk
Follow-up · day 3: Only to people who didn't open
Deliverability: Send to verified contacts only; avoid link shorteners; keep one primary link.

Example recommendation

Your bounce rate increased over the last 7 days

It rose from 1.1% to 3.4% across 12,480 emails. Consider suppressing recently bounced addresses and reviewing list quality before the next send.

Verify a list

Plan a stricter DMARC policy

Your record is in monitoring mode (p=none). When reports show all legitimate mail passing, move to quarantine.

An advisor that reads your real numbers

The Deliverability Advisor looks at what we actually measure for your account — SPF, DKIM and DMARC lookups, bounce, complaint and delivery rates, block-list checks and reverse DNS — and tells you what to fix first.

It never invents a metric, and it never promises inbox placement. Mailbox providers make their own decisions; we help you give them every reason to trust your mail.

Works with n8n, Zapier and Make

Use InboxRoads as the email step in the workflows you already run. Verify a lead, send an email, enrol a contact in an automation, and get signed webhooks back for every open, click and bounce.

Today these connect through our REST API and webhooks (labelled "API supported"); there are no native app nodes yet. A ready-to-import n8n workflow is included in your account.

Standard 14-day: daily cap

Day 1: 50 → day 14: 5,000 messages. Pauses automatically above 5% bounces or 0.3% complaints.

IP warm-up that watches its own health

Pick an IP, a domain and a plan. Volume is capped by the sending router and increases one day at a time — only while bounce and complaint rates stay under your thresholds. Custom schedules are supported.

Warm-up builds a sender's history responsibly. It is not a way to get around spam filters.

Measure everything, from real events

Sent, delivered, hard and soft bounces, opens, clicks, unsubscribes and complaints — by campaign, by sending domain, over time, and by mailbox provider.
