Automate Your B2B Sales From Lead Gen to Follow-up.
Stop letting webinar lists and trade show business cards collect dust. Nurture leads automatically and generate a steady stream of sales appointments.
No credit card required. Setup takes minutes.
Built for B2B sales teams like yours
Solve these B2B sales bottlenecks:
Neglected Event Leads
You scan hundreds of badges at trade shows, but your sales team never sends the follow-up emails.
Cold Leads Stay Cold
Past prospects are forgotten because you lack an automated system to send them relevant content over time.
Sales Rep Burnout
Your best closers are wasting hours formatting emails and making cold calls instead of running actual meetings.
What happens after the business card exchange
Leads from trade shows and webinars lose value the longer they sit untouched. Mail Assist automates everything from the thank-you email to booking a call, and flags hot leads based on click behavior — so your reps reach out exactly when interest is highest.
Your 24/7 Automated Sales Assistant
From AI lead extraction to behavioral step-campaigns, we automate the busywork so you can focus on closing.
Post-Webinar/Event Sequences
Import your attendee list and automatically trigger a 'Thank you' email, followed by a whitepaper download and meeting request.
Lead Scoring & Hot Alerts
Detect when a prospect clicks your pricing page multiple times and instantly alert your sales team to call them.
Result: 2.5x More Appointments
*Case Study: By automating nurturing and calling only hot leads, our B2B clients see a 2.5x increase in booked meetings.
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.
