| Mejor para | Correo electrónico frío de alto volumen | Multichannel sales outreach |
1. Sending Scale and Email Accounts
Instantáneamente: Every paid plan allows an unlimited number of sending accounts. You can connect hundreds of inboxes and rotate sending volume across all of them. This is designed for agencies and teams running high-volume cold email campaigns where deliverability at scale matters most.

Ataque de correo: Mailshake limits sending volume and caps email accounts based on your plan tier. The Starter plan includes basic sending, while the Email Outreach plan lifts the cap. It’s enough for small sales teams but not built for running hundreds of inboxes in parallel.
2. Lead Generation and Contact Database
Instantáneamente: The AI-Powered Lead Finder connects to a B2B lead database with over 450 million contacts. You can filter prospects by job title, company size, industry, and location, then push them into a campaign in a few clicks. This helps generate leads without paying for a separate email finder tool.

Ataque de correo: The Data Finder pulls verified business emails and phone numbers. It works well for finding prospects one-off or in small batches. However, the contact pool is smaller than Instantly’s 450M+ database, which matters if your lead generation depends on wide reach.

3. Entregabilidad del correo electrónico
Instantáneamente: Inbox rotation distributes volume across multiple sending accounts automatically. Combined with automatic warm-up, this keeps sender reputation strong and avoids spam filters. Based on published benchmarks, small businesses report inbox placement rates around 85.3% when scaling outreach through Instantly.

Ataque de correo: Mailshake includes email deliverability tools, sending schedules, and throttling controls. Features help keep bounce rates low and maintain sender health. It lacks the aggressive inbox rotation Instantly provides, but it’s enough for a small team sending hundreds of emails per day rather than thousands.

4. Multichannel Outreach (LinkedIn and Phone)
Instantáneamente: Instantly focuses on email only. There’s no native LinkedIn automation or phone dialer. If you need multichannel sequences, you’ll need to layer on another tool or handle those channels manually outside the platform.
Ataque de correo: The Email Outreach plan adds LinkedIn automation and a built-in phone dialer. Sequences can mix email steps with LinkedIn connection requests and scheduled call tasks. This is the main reason small sales teams pick Mailshake over cold-email-only tools.

⚠️ Advertencia: LinkedIn automation and the phone dialer require Mailshake’s Email Outreach plan at $45/month. The Starter plan at $25/month is email-only and won’t give you multichannel sequences.
5. AI Personalization and Email Writing
Instantáneamente: Hyper-Personalization with AI generates custom opening lines and personalized messages using data from each prospect’s profile. You can also set AI prompts that tailor messages across the full campaign. This helps at volume, where writing manual intros for every contact isn’t feasible.

Ataque de correo: SHAKEspeare is Mailshake’s AI email writer. It drafts cold email copy, subject lines, and call to action buttons based on your input. It’s a solid starting point when you’re stuck on copy, though heavy personalization still requires your own writing on top.

6. Automated Follow-Ups and Sequences
Instantáneamente: The campaign builder supports automated follow ups, A/B testing on subject lines and body copy, and branching logic based on replies. Campaigns stop automatically when a prospect replies, opens a link, or marks the email as read. Auto responders also handle bounces and out-of-office replies.

Ataque de correo: Sequences include automated follow-up emails, conditional steps based on opens and clicks, and auto responders. The visual sequence builder is easy to learn for new users. A/B testing is available on all email automation tools, though the interface is less granular than Instantly’s.

7. CRM and Lead Management
Instantáneamente: A built-in Automated CRM tracks replies, assigns leads to pipelines, and flags hot prospects. You can move prospects through stages without exporting data to another tool. Native integrations also connect with external CRMs for teams that already have a sales stack in place.

Ataque de correo: Mailshake integrates with major CRM tools like Salesforce and Pipedrive for two-way data sync. It also has Lead Catcher, a lightweight inbox for managing replies directly inside Mailshake. It doesn’t have a full CRM of its own, so you’ll rely on the integrated CRM for pipeline management.

8. Analytics and Real-Time Insights
Instantáneamente: Campaign Analytics tracks open rates, click through rates, reply rates, and bounce rates in real time. You can compare campaigns side by side and spot which subject lines or templates drive the best outcomes. Dashboards are designed for teams managing many campaigns at once.

Ataque de correo: Mailshake shows open rates, clicks, replies, and A/B test results for each campaign. Reports are straightforward and surface the basics without extra setup. Deeper cross-campaign analysis is more limited compared to Instantly’s dashboards.
9. Integrations and Tool Compatibility
Instantáneamente: Native integrations cover major CRMs, Zapier, webhooks, and Hyperise for personalized images. You can sync replies, opens, and lead status with your existing tools. The platform is built to play nicely with other marketing tools in your stack.
Ataque de correo: Mailshake integrates with Salesforce, Pipedrive, HubSpot, Zapier, and Hyperise. Both Instantly and Mailshake use the Image embed method to integrate with Hyperise, letting you add personalized images to outreach. Two-way CRM sync is the strongest point here.

Precios y costos
Compare los planes de precios uno al lado del otro.
| Plan | Instantáneamente | Mailshake |
|---|---|---|
| Entrada | Growth — $30/month | Starter — $25/month |
| Nivel medio | Hypergrowth — $77.60/month | Email Outreach — $45/month |
| Nivel superior | Light Speed — $286.30/month | — |
| Empresa | Costumbre | Contactar con Ventas |
Instantáneamente: The flat-fee structure is where Instantly wins on cost. A $30/month Growth Plan covers 1,000 active leads and 5,000 emails with unlimited sending accounts. Even the Hypergrowth Plan at $77.60/month covers 25,000 leads and 100,000 emails. Adding more team members doesn’t raise the price.
Ataque de correo: Mailshake’s Starter plan at $25/month is the cheaper entry point, but it’s a stripped-down cold email plan. To unlock automation, mail merge, multichannel sequences, and the phone dialer, you need the Email Outreach plan at $45/month. For teams that genuinely need phone and LinkedIn automation, $45/month is a reasonable cost to combine three channels in one tool.

What Our Review Didn’t Cover
This comparison focused on solo founders and small sales and marketing teams. We didn’t evaluate enterprise-level features like custom SLAs, dedicated IPs at large volume, or custom pricing negotiations. Deliverability results vary by industry and list quality, so your open rates and click through rates may differ from published benchmarks. If you’re running outreach in regulated industries or sending to strict markets, test both tools with a small list before committing.

Preguntas frecuentes
¿Merece la pena Instantly AI?
Instantly is worth it for teams running cold email campaigns at scale. The flat-fee pricing, unlimited sending accounts, and built-in lead database help sales teams save time compared to stitching together other platforms. For email marketing focused on reaching new customers and driving replies that drive conversions, it’s one of the cleaner all-in-one picks to maximize pipeline without per-seat fees. Solo senders with very low volume may find the entry plan overkill.
¿Mailshake funciona con Outlook?
Yes. Mailshake connects to Outlook, Gmail, and most SMTP providers. You link your account once, and the tool sends cold emails and automated follow up emails from your address as if you sent them manually. The dashboard acts like a personal assistant for your sequences and gives real time insights into opens, clicks, and replies.
¿Cuántos correos electrónicos puedes enviar con Instantly?
Volume depends on the plan. The Growth Plan covers up to 5,000 emails per month, Hypergrowth extends to 100,000, and Light Speed handles much more. Since Instantly allows an unlimited number of sending accounts, you can scale by adding more inboxes and reach new customers quickly. Campaigns also let you enroll prospects automatically from the built-in lead database, so list building doesn’t bottleneck your sending.
¿Es Apollo mejor que Instantly?
Apollo and Instantly solve different problems. Apollo is a full sales engagement platform with a larger database and a dialer. Instantly is focused on cold email scale with unlimited sending accounts. Compared to Mailshake Instantly also leans more toward pure email, while Apollo’s basic plan covers sales workflows too. For better outcomes on multichannel sales pick Apollo; for email-first outreach pick Instantly.
¿Para qué se utiliza Mailshake?
Mailshake is used for cold email outreach, sales sequences, and multichannel prospecting. Small sales and marketing teams use it to book meetings by combining email, phone, and LinkedIn touches. It’s especially popular among reps who want email campaigns and phone calls in one workflow. Teams researching Mailshake alternatives often land on Instantly, Reply IO, or Woodpecker depending on their budget and channel mix.
