One platform for the whole cold-email workflow

Everything you need to land in the inbox
and book more meetings

Verification, sequences, warmup, a unified reply inbox, a sales pipeline, analytics and team workspaces — all in one place, so your list, your sending and your replies never live in five different tools again.

Feature 01 — Multi-step Sequences

Cold campaigns that follow up automatically

Build multi-step sequences with day-based delays, A/B variants per step, and mailbox rotation. Follow-ups thread onto the same conversation, and the whole run stops the moment a prospect replies.

  • Unlimited steps & A/B variants. Test different angles per step; the winner surfaces in analytics.
  • Sticky mailbox rotation. Each prospect keeps one sender, so follow-ups arrive in one thread.
  • Timezone-aware windows. Sends respect each sequence's days and hours — no 3 a.m. emails.
  • Auto-stop on reply. Reply detection halts the sequence instantly.

Use case

A B2B SaaS team loads 400 prospects, writes a 4-step sequence, attaches two mailboxes, and hits activate. The platform paces sends inside business hours, rotates mailboxes, and stops anyone who replies — hands-off.

Feature 02 — Content Guide & Sequence Score

Deliverability coaching as you type

A live Content Guide grades every email on subject length, word count, personalization, links, spam words and image ratio. A Sequence Score rolls up copy quality, spacing, rotation and reply-handling into one number — so you fix problems before you send, not after.

  • Live metric bars. Every keystroke re-scores the email against cold-email best practice.
  • Merge tags & spintax. {{First Name|there}} fallbacks and {spun|varied} copy per recipient.
  • Sequence Score 0–100. Seven weighted factors with concrete, actionable tips.
  • Built-in copy assistant. Generate subject lines, variants and whole sequences in a click.

Use case

A founder writing their first cold email sees 'Personalization: 1 merge tag — Average' and 'Spamminess: 0 — Excellent'. They add a company mention, watch the score climb, and send with confidence.

Feature 03 — Email Verification

Clean every address before you send

A 6-check verification engine — syntax, MX, SMTP handshake, disposable detection, role flagging, and catch-all probing, applied as each domain warrants. Prospects verify on import, and invalid addresses are never emailed, so bad data can't burn your sending reputation.

  • 6 independent checks. From MX records to live SMTP handshakes and catch-all probing.
  • Verify on import. CSV uploads are checked automatically; bad addresses can't reach a send.
  • Bulk verification. Upload thousands of addresses and download a clean list when done.
  • Standalone API. Use it inside sequences or hit it directly with an API key.

Use case

An agency imports a 5,000-row purchased list. 600 addresses come back invalid and are auto-suppressed before the first send — protecting the domain reputation the whole account depends on.

Feature 04 — Email Warmup

Warm up new mailboxes automatically

New mailboxes need reputation before they can send cold. The warmup network has mailboxes email each other with natural conversations, open and reply to them, and rescue messages from spam — building a real sending history so your cold campaigns land in the inbox.

  • Natural conversations. Warmup threads read like real, human conversations, never templated spam.
  • Inbox engagement. Warmup mail is opened, moved out of spam, and replied to automatically.
  • Gradual ramp-up. Daily volume climbs on a schedule, mirroring how real accounts age.
  • Reputation score. Every mailbox gets a live health score from inbox-placement data.

Use case

A freshly-bought Gmail joins warmup on day one at 5 emails/day. Two weeks later it's landing in inboxes with a 100 reputation score — ready to carry a live sequence.

Feature 05 — Unified Inbox

Every reply, every mailbox, one place

Replies from all your sending accounts land in one unified inbox. The platform detects them, matches them to the right sequence by thread headers, categorises sentiment, and stops the sequence — so a prospect who says 'yes' never gets a follow-up meant for someone who ignored you.

  • Cross-mailbox threading. In-Reply-To/References matching ties replies to the exact enrollment.
  • Sentiment tagging. Positive / neutral / negative, with opt-out requests auto-suppressed.
  • Reply from the right account. Answer inline; it sends from the mailbox that owns the thread.
  • Auto-reply filtering. Out-of-office bounces don't falsely stop a sequence.

Use case

A sales rep opens the inbox to five green 'Positive' replies, answers each in two clicks from the correct mailbox, and moves on — no switching between five Gmail tabs.

Every reply, every mailbox, one place
Feature 06 — Sales Pipeline (CRM)

Turn positive replies into a pipeline you can close

A drag-and-drop deal board tracks every opportunity from first reply to closed-won. Positive replies from your sequences become leads automatically, so nothing hot slips through the cracks — no separate CRM subscription required.

  • Kanban deal board. Six stages from Lead to Won/Lost; drag a card to move a deal.
  • Auto-created leads. A positive reply opens a deal with the prospect's details attached.
  • Value & forecast tiles. Open pipeline value and won revenue summarised at the top.
  • Workspace-scoped. Each team or client workspace keeps its own private pipeline.

Use case

A rep gets three positive replies overnight; each already sits in the 'Lead' column at 9 a.m. They drag the qualified one to 'Proposal', and the forecast tile updates instantly.

Feature 07 — Inbox Placement Testing

Know where you land — inbox or spam

Before you scale a campaign, run a placement test: the platform sends a tagged email to seed mailboxes across the major providers and reports exactly where each one landed. You catch a spam-folder problem before it costs you a whole campaign.

  • Per-provider breakdown. See inbox vs spam across Gmail, Outlook, Yahoo and more.
  • One placement score. A single percentage tells you if a campaign is safe to send.
  • Run before you scale. Test a new domain or template on seeds, not on real prospects.
  • Tied to warmup. Placement data feeds each mailbox's live reputation score.

Use case

Before a 2,000-send push, a team runs a placement test and sees Outlook at 40% spam. They fix SPF alignment, retest to 100% inbox, then launch — campaign saved.

app.emailidentity.io/dashboard/email/placement

Feature 08 — Analytics

Know which step and which variant wins

Per-sequence analytics show sent, open, click, reply and bounce rates over time, plus a per-step breakdown with A/B variant comparison. The winning variant is flagged automatically, so you double down on what actually books meetings.

  • Activity trend chart. Daily sent / opened / replied, built from an append-only event log.
  • Per-step breakdown. See exactly where prospects engage or drop off.
  • A/B winner detection. The higher reply-rate variant is badged 'Winning' at a glance.
  • Mailbox health. Bounce and complaint rates per sending account.

Use case

After 200 sends, analytics show variant B's 'question-led' subject pulling a 9% reply rate vs A's 3%. The team pauses A and scales B — data, not guesswork.

Feature 09 — Teams & Workspaces

Shared workspaces for whole teams

Create team workspaces where sequences, prospects and the inbox are shared with everyone you invite. Existing users join instantly; new emails get an invite link. Your billing plan governs the whole team's limits, and data is fully isolated between workspaces.

  • Shared outreach. Sequences, prospect lists and the inbox are visible to every member.
  • Roles & invites. Owner / admin / member, with instant-join for existing users.
  • Strict isolation. Switch workspaces and the whole app re-scopes — no data leakage.
  • One-click switcher. Personal and team workspaces, right in the sidebar.

Use case

An agency runs each client in its own workspace — client A's prospects and replies never touch client B's — while the agency owner's plan covers them all.

app.emailidentity.io/dashboard/settings/team
Shared workspaces for whole teams
Feature 10 — Integrations & API

Wire your outreach into the tools you already use

Connect Zapier, Make, n8n, HubSpot and Slack through open webhooks, and push or pull data with a REST API. Fire a Slack message on every positive reply, create a HubSpot contact when a deal is won, or add prospects from any tool — no custom code required.

  • Outreach event webhooks. Replies, positive replies, unsubscribes, completed sequences and won deals.
  • HMAC-signed payloads. Every webhook is signed so your automations can verify it's really us.
  • REST API + playground. Create prospects, read the inbox, manage the pipeline — test it live in-app.
  • Works with any platform. Zapier, Make, n8n, HubSpot, Slack and anything that speaks webhooks.

Use case

A RevOps lead connects a 'positive reply' webhook to Slack and a 'deal won' webhook to HubSpot. The whole team sees hot leads instantly, and the CRM updates itself.

Feature 11 — Templates & Sending

A template library and sender that do the heavy lifting

A hand-built Professional collection of responsive templates — every variable editable, opt-out footer included — plus a builder to save your own. Send one-off emails or bulk campaigns through your own SMTP or a Gmail OAuth connection, with suppression handling built in.

  • Pro template library. Onboarding, transactional, marketing and plain-text outreach templates.
  • Visual builder + HTML. Edit brand colour, copy and merge tags with an instant preview, or drop in raw HTML.
  • Bulk send & A/B subjects. Send to thousands with per-recipient personalisation and subject testing.
  • Automatic suppression. Unsubscribes and bounces are never emailed again.

Use case

A team clones the 'Cold Intro' plain-text template, tweaks two lines, saves it, and reuses it across every new sequence — consistent voice, zero re-writing.

Feature 12 — Verification API & Developer Tools

Verify email from your own app in one request

The same 6-check engine that cleans your prospect lists is available as a REST API. POST an address with your key and get a structured verdict in under 3 seconds — no SDK required. Manage keys, test calls live in the playground, and keep a searchable history of every check.

  • One-call verify endpoint. POST an email, get syntax, MX, SMTP, disposable, role and catch-all results as JSON.
  • API keys you control. Generate ei_live_ keys, scope them, and revoke any key instantly.
  • Live API playground. Fire real requests from your dashboard with cURL, Node.js and PHP samples.
  • Full check history. Every verification is stored, searchable and exportable to CSV.

Use case

A signup form calls the verify API on submit. Disposable and invalid addresses are rejected before the account is created — the list stays clean from day one, with every check logged in history.
