What is EterMail? AI email marketing that knows your brand

EterMail is an email marketing platform for ecommerce stores, SaaS products and mobile apps. It brings four jobs into one place: campaigns to your subscribers, automated flows triggered by what customers do, cold outreach from your own mailboxes, and a unified inbox for every reply. AI does the drafting; you approve every send.

Why we built it

Most teams that sell online end up with three or four email tools: one for newsletters, one for automations, another for cold outreach, and a shared mailbox for replies. Each tool has its own contact list, its own idea of who unsubscribed, and its own bill. Brand voice drifts because every email starts from a blank page.

EterMail starts from your brand instead. Enter your website and the AI extracts your voice, logo, colors and featured products. Every email it drafts follows that profile, and product blocks come straight from your store.

What you can do with it

Campaigns

Pick a template or ask the AI for a first draft, adjust it in the editor, and send to a segment or all subscribers. Subject lines can be A/B tested: a share of the audience receives each subject, and the version with more clicks goes to everyone else. Campaigns can be delivered at the same local time in each recipient's time zone.

Automated flows

Ready-made templates cover the moments that matter: welcome series, browse abandonment, abandoned checkout, post-purchase cross-sell and win-back. SaaS products and apps can also trigger a flow from any custom event they send, such as Trial Started. You approve a flow once and it keeps running; editing it requires a fresh approval.

Cold outreach

Connect your own Google, Microsoft or SMTP mailboxes. EterMail ramps new mailboxes up gradually, keeps each one under a daily cap, sends only inside business hours, and stops a sequence the moment the prospect replies. The AI writes a personalised opening line for each company. Cold email uses separate mailboxes and domains from your marketing email, so one never damages the other's reputation.

Unified inbox

Replies to campaigns and outreach land in one inbox. The AI classifies each conversation (interested, question, not interested, out of office and so on) and drafts a reply that you can edit and send from the original mailbox.

How you connect your data

• Shopify: create a read-only app for your store and enter its Client ID and secret. Customers, consent, orders, products and unfinished checkouts sync every 15 minutes. See the Shopify setup guide.
• SaaS and apps: send users and events from your server with the identify and track API, which follows the Segment spec. See the API documentation.
• Any website: use a hosted signup form with double opt-in, or import a CSV with a stated consent basis.

Built to protect deliverability

An email only works if it reaches the inbox. These safeguards are on by default:

• one-click unsubscribe that meets Gmail and Yahoo sender requirements;
• consent re-checked at the moment of sending, so someone who unsubscribed after you scheduled a campaign is never emailed;
• a consent record with source and time for every subscription;
• automatic pause when bounces or complaints spike;
• a pre-send check for your sending domain, unsubscribe link and postal address.

How pricing works

On Starter, Growth and Pro, your monthly plan converts in full into credits at 1,000 credits = $1; Ultra includes 149,000 credits a month, and cold email isn’t charged per send. A marketing email costs 2 credits and a cold email 5 credits; AI features are billed by actual usage. Plans start at $0, and you can try Growth free for 14 days with 2,000 credits (a card is required; cancel before the trial ends and you pay nothing). See pricing for details.
