Great fit for EC store owners like you
Are you ignoring these eCommerce missed opportunities?
70% Cart Abandonment Rate
Shoppers add items to their cart but leave right before checkout, forgetting to complete the purchase.
Low Lifetime Value (LTV)
Customers buy once and disappear. You aren't reminding them to restock consumables.
Zero Social Proof
You don't have the time to manually email customers asking for reviews, hurting your store's conversion rate.
For the customer who almost bought, and left it in the cart
Most cart abandonment is just forgetting — not lost interest. The right reminder at the right time wins that sale back. Mail Assist connects to your purchase data to automate recovery and cross-sell, cutting lost sales while lifting LTV.
The Automated Revenue Engine
Connect with your purchase data to automate every essential customer communication.
Cart Abandonment Recovery
Automatically send an Email or LINE message 1 hour after a cart is abandoned, strongly encouraging them to finish checking out.
Cross-sells & Replenishment
Set up triggers like 'Send a 30-day refill reminder' or 'Recommend Product B if they bought Product A'.
Result: 20% Boost in Cart Recovery
*Case Study: Our automated recovery sequences successfully convert 20% of abandoned carts into completed sales.
安心の自己管理型（ゼロ・トラスト設計）
大切な顧客リストを弊社サーバーに過度に依存させず、お客様ご自身でJSON形式の完全データをバックアップ・管理できる設計を採用しています。
これにより、中央集権型サーバー特有のデータ消失・情報漏洩リスクを根本から排除し、極めて高いセキュリティと安心感を実現しました。
メール・LINEを1つの画面で一元管理
メールだけでなくLINE公式アカウントへの配信・問い合わせ対応も同じ画面で完結。窓口ごとに別ツールを開き直す手間をなくし、どの連絡先に何をいつ送ったかを一箇所で管理できます。
AIが問い合わせ返信の下書きを自動作成
ホームページ経由の問い合わせに対し、AIが内容を読み取って返信文の下書きを自動生成。担当者は内容を確認して送るだけなので、一次対応のスピードと品質が大きく向上します。ステップ配信も開封・クリックなどの行動に応じた高度な条件分岐に対応。

Why Mail Assist actually gets delivered (the technical reason)
The number one reason emails don't arrive is guilt by association — other users' spam on a shared server dragging your reputation down with it. We build in the latest authentication standards by default, giving you a clean sending environment.
An isolated environment via dedicated domain design
Prevents guilt-by-association spam flags from shared IPs. We build a sending domain environment that's entirely yours, fully compliant with SPF/DKIM/DMARC, maintaining high reputation with providers.
An intuitive UI that needs no manual
No complex English-only menus like overseas tools, no clunky legacy screens. A Notion-like editor and timeline UI let you build scenarios intuitively.
No more runaway usage-based pricing
Typical systems balloon in cost as your list or send volume grows. Our Business plan is a flat rate up to 10,000 contacts — the bigger your list, the better your margins.
Unbeatable ROI vs Legacy Tools
See why B2B businesses are switching to Mail Assist.
| Feature | Legacy Email Tools | Overseas high-end tools | Mail Assist |
|---|---|---|---|
| Behavior Tracking | Manual Management Only | Supported, but the entire settings UI is in English and hard to follow | Auto-detect Opens & Clicks |
| Deliverability | Shared IPs (High spam risk) | Shared IP (dedicated IP costs $700+/mo as an add-on) | Dedicated Domain Setup |
| Price for 10k Contacts | ~$130 to $150 / mo | Feature-rich but complex, with a steep learning curve | Flat $89 |
| Marketing Automation | Premium Tiers Only | Costs spike sharply with volume (often $300+/mo) | Advanced Step-Email Included |
| Migration support from your existing system | Manual export and CSV formatting required | Data migration and setup are largely self-service | One-click CSV import with 24/7 full AI support |

Frequently Asked Questions
What is the Step-Email (Auto-Delivery) feature?
It automatically sends the most optimal emails in sequence based on pre-set rules or customer behavior, such as 'immediately after registration', '3 days later', or 'when a link is clicked'. It fully automates everything from lead nurturing to closing.
Will this actually improve my open rates?
Yes. By forcing dedicated domain setups and isolating your sending reputation from other users, your emails are far more likely to land in the primary inbox instead of spam.
Do I need technical skills to set this up?
Not at all. Our intuitive dashboard makes campaign creation a breeze, and we provide step-by-step guides for DNS configuration to ensure perfect deliverability.
