Smartleadとは何ですか？
Smartlead is a cold email automation tool built to turn cold emails into reliable revenue streams.
It focuses entirely on email deliverability, lead generation, and cold email automation — at a scale most tools can’t reach.
Smartlead allows unlimited email accounts, unlimited email warm-up, and consolidates all outreach channels into a centralized master inbox called the “unibox” — a unified inbox that manages all interactions with potential customers from a single location.
It also supports engagement across multiple channels including email, LinkedIn, SMS, and WhatsApp — though email remains the primary focus for generating more leads.
Smartlead’s automated warmup mimics human-like conversations to sustain a positive sender reputation, which helps emails land in the primary inbox rather than the spam folder.
Trusted by over 87,000 businesses in 2026, it targets agencies and high-volume senders who need flexible pricing and a user-friendly interface for managing multiple campaigns. A custom plan is available for teams with enterprise-level outreach needs.

- 無制限のメールアカウント: Connect unlimited sender accounts at no extra cost. This lets you expand cold email outreach without restrictions imposed by a mailbox limit.
- AIを活用したウォーミングアップ： Smartlead’s warmup functionality enhances your sender reputation by maintaining humanized email sending patterns. Emails land in the primary inbox, not the spam folder.
- 集中管理型マスター受信トレイ： The unibox consolidates all outreach channels, responses, sales follow-ups, and conversions into one single location for easier lead management.

機能比較
Let’s compare Mailshake and Smartlead across 9 key areas that matter most to sales teams running cold outreach.
| 特徴 | メールシェイク | スマートリード |
|---|---|---|
| 開始価格 | ユーザー1人あたり月額25ドル | $32/month (unlimited accounts) |
| 無料トライアル | ❌ なし | ✅ 14日間 |
| 無制限のメールアカウント | ❌ One per seat | ✅ すべてのプラン |

| A/Bテスト | ✅ | ✅ |
| CRM統合 | ✅ Native (Salesforce, HubSpot) | ✅ API & webhooks |
| 最適な用途 | マルチチャネル販売チーム | 大量メール配信代理店 |
1. メール配信率
スマートリード: Smartlead employs unique IP rotating for each campaign to protect your sender reputation. Its AI-powered warmup mimics human-like conversations so emails land in the primary inbox rather than the spam folder. SmartDelivery and SmartAdjust monitor inbox placement in real time and adjust sending behavior to protect against low reply rates — features that give agencies precise control over email deliverability.
メールシェイク: Mailshake includes email warm-up, verification, and throttling that mimic natural sending patterns to avoid spam filters. It also allows users to connect an existing email provider, which helps deliverability by sending from a trusted inbox. However, some users have reported issues with email deliverability affecting the success rate of outreach campaigns — a known limitation that has pushed some mailshake users toward alternatives.
💡 テスト結果： Smartlead’s dedicated servers and IP rotation give it an edge for teams sending high volumes of cold emails. If getting emails into prospect inboxes is your top priority, Smartlead’s deliverability tools are more advanced.
2. メールアカウントの制限
スマートリード: Every Smartlead plan includes unlimited email accounts. You can connect Gmail, Outlook, or custom SMTP servers without extra cost. This allows teams to expand their cold email outreach without restrictions imposed by a mailbox limit — a major advantage for agencies running multiple campaigns across many sender accounts.
メールシェイク: Mailshake allows one mail account per seat. If your sales team needs 10 sending accounts, you pay for 10 seats. At the Email Outreach plan rate, that’s $450/month for 10 accounts — versus Smartlead’s flat $32/month for unlimited mailboxes. This per-user subscription model makes Mailshake expensive as teams grow.
⚠️ 警告： If you plan to scale beyond 3–4 sending accounts, Smartlead’s unlimited model saves significant money. Calculate your total cost at scale before committing to Mailshake’s per-user model.
3. LinkedInの自動化
スマートリード: Smartlead does not include native LinkedIn automation. It supports engagement across multiple platforms — including SMS and WhatsApp — but LinkedIn outreach requires a third-party tool like 拡大 or Dripify. For teams whose target audience is heavily active on LinkedIn, this is a meaningful gap.
メールシェイク: Mailshake allows users to automate LinkedIn outreach tasks like sending connection requests and LinkedIn messages from the same sequence as cold emails. Sales reps can view prospect inboxes on LinkedIn alongside email activity — all from a central dashboard. This is a genuine differentiator over pure email tools.
📌 注記： LinkedIn automation is exclusive to Mailshake’s Sales Engagement plan ($85/month annual). Teams on the Starter or Email Outreach plans cannot access LinkedIn messages or connection requests.
4. Phone Dialer & Cold Calling
スマートリード: Smartlead has no phone dialer. It is a cold email software only. Sales teams that need to integrate cold calling into their outreach efforts must use a separate tool like Aircall or JustCall — which adds cost and management overhead.
メールシェイク: Mailshake includes a power phone dialer that lets sales reps make calls directly from the platform. The dialer records calls automatically and syncs notes to your CRM. Unlimited free dialer minutes come with the Sales Engagement plan, which means phone calls become part of a single multichannel sequence rather than a separate workflow.
5. AI Email Writing & Personalization
スマートリード: Smartlead allows users to personalize emails using variables and spintax to enhance engagement. Its AI-optimized sending 能力 adjusts the timing and strategy of outreach campaigns based on data-driven insights. There is no built-in AI email writer — you bring your own copy — but hyper personalization through advanced integrations is well supported.
メールシェイク: Mailshake’s SHAKEspeare AI helps users generate custom email copy and subject lines based on their campaign goals. The in-app copy analyzer scores emails before sending. Mailshake also supports mail merging — a mail-merging feature that lets sales teams create personalized emails and LinkedIn messages at scale without writing each one manually.
6. リード管理
スマートリード: The centralized master inbox — Smartlead’s “unibox” — consolidates all outreach channels, responses, and follow-ups into a single location. This makes managing qualified leads across multiple campaigns straightforward. The Pro Plan also includes a custom CRM for tracking your sales pipeline. Smartlead’s API and automation infrastructure also let the Smartlead team connect to a data enrichment tool or external CRM for detailed analytics.
メールシェイク: Mailshake’s Lead Catcher feature automatically identifies the most engaged leads from your outreach campaigns and surfaces them in a lead drivers dashboard. Sales reps can filter prospects by buyer persona, job titles, or engagement level and focus their time on contacts most likely to convert. Native integrations with Salesforce and HubSpot keep the sales pipeline updated in real time.
7. Automated Follow-Ups & Sequences
スマートリード: Smartlead’s follow-up automation runs multi-step cold email sequences that stop automatically when a prospect replies — a critical feature for avoiding double-touching leads. Email personalization advanced scheduling lets you set send windows by time zone, keeping outreach relevant to your target audience. Smartlead’s cold email API and automation infrastructure transform campaign creation and management for high-volume senders.
メールシェイク: Mailshake supports cold email automation with multi-step campaigns that also stop when a prospect replies. Users can set automated follow-ups based on a schedule they define — by day, time, or trigger. The platform provides analytics to track opens, replies, and clicks across outreach campaigns, and includes A/B testing for subject lines and email body copy.
8. Agency & White Label Features
スマートリード: Smartlead offers custom whitelabeling and client sub-accounts for agencies — you can brand the platform as your own and manage each client’s outreach from a separate sub-account. The Pro Plan includes unlimited client additions for $29 per client per month, making it a purpose-built cold email tool for agencies that provide cold emailing as a service.
メールシェイク: Mailshake has no white label option. Agencies managing multiple clients need to create separate accounts for each, which adds complexity. Mailshake works much better for in-house sales teams than for agencies running multiple campaigns on behalf of other businesses.
9. Pricing & Cost Comparison
Here’s how the plans stack up side by side:
| プランの種類 | メールシェイク | スマートリード |
|---|---|---|
| エントリーレベル | $25/month (Starter, annual) | $32/month (Basic Plan) |
| 中級クラス | $45/month (Email Outreach, annual) | $78/month (Pro Plan) |
| 全機能 | $85/month (Sales Engagement, annual) | 月額144ドル（スマートプラン無制限） |
| 企業 | 該当なし | 月額315ドル（プライム会員無制限） |
スマートリード: Smartlead’s flexible pricing accommodates both small businesses and large enterprises. At $32/month, the Basic Plan includes unlimited email accounts and unlimited email warm-up — features that would cost hundreds per month on Mailshake at scale. The cost-effective pricing model is one of the main reasons growing teams choose Smartlead over other cold email tools.
メールシェイク: Mailshake starts cheaper at $25/month per user but includes only one email account per seat. For solo reps or very small sales teams, Mailshake is the more affordable sales engagement plan. For teams with multiple mail accounts and multiple campaigns, the per-user model quickly adds up — making Mailshake’s pricing structure a common complaint among mailshake users at scale.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| 大量のコールドメールを大規模に送信する | スマートリード | アカウント無制限、AIウォームアップ |
| LinkedIn + Email + Phone outreach | メールシェイク | 真のマルチチャネルプラットフォーム |
| 最高のメール配信率 | スマートリード | IP rotation, SmartDelivery |
| Agency white labelling | スマートリード | Custom branding + sub-accounts |
| 料金を支払う前に無料トライアルをご利用いただけます。 | スマートリード | 14-day trial vs no trial |
| Simple solo outreach | メールシェイク | Easier setup, data finder built in |
💰 あなたの予算
Mailshake starts $7/month cheaper per seat, but costs multiply fast as your sales team grows. Smartlead’s cost-effective pricing stays flat even with unlimited sender accounts — making it the better value for teams running multiple campaigns or many mail accounts.
🔌 あなたの技術スタック
Mailshake offers native integrations with Salesforce, HubSpot, and パイプドライブ, which suits established teams already using those CRMs. Smartlead integrates with CRM systems via APIs and webhooks — flexible but requires more technical skills to configure for accurate data synchronization.
📝 あなたのアウトリーチ戦略
If your outreach strategy involves cold calling, LinkedIn messages, and personalized emails all together — Mailshake is the right tool. If your outreach efforts are email-only at high volume, Smartlead’s cold email automation is more purpose-built for that specific need.
🎓 あなたの経験レベル
Mailshake has a user friendly interface that many sales reps pick up quickly. Smartlead’s interface has been described as unintuitive by beginners — it has a learning curve but rewards users who invest time in the platform. Both tools have a support team and documentation to help new users.
🆓 無料トライアルとデモ
Smartlead offers a 14-day free trial with full access — no credit card required. Mailshake does not offer a free trial, making it harder to evaluate before committing. If you want to test cold email software before paying, Smartlead is the clear choice.
🛟 サポートオプション
Both platforms have a support team, but neither has standout response times at lower-tier plans. Mailshake’s customer support has been reported as slow to respond. Smartlead’s active support is better on higher-tier plans — the Pro Plan includes priority support for agencies.

What Our Review Didn’t Cover
This comparison focused on individual sales reps and small-to-mid-size agencies running cold email outreach. We did not evaluate enterprise SSO, bulk licensing, or how either tool performs for teams with 50+ users. Our observations are based on the May 2026 versions of both platforms — features, pricing, and recipients per campaign limits may have changed since publication. If you manage a large enterprise sales engagement platform rollout, your priorities may differ from what we’ve covered here.
