I tested 7 Instantly alternatives: Here’s the best cold email software for 2025

Let me guess. You signed up for Instantly.ai thinking you’d found the holy grail of cold outreach. Unlimited email accounts, easy scaling… it all sounded great on paper. But now you’re spending half your day reconnecting accounts and the other half in a frustrating chat with a support agent who seems to be avoiding your questions.

Your emails are landing in spam, your reply rates have fallen off a cliff, and that "optional" CRM just magically doubled your monthly bill.

That’s exactly why I went looking for a replacement and decided to put the most popular Instantly alternatives to the test. This isn’t just another roundup; it’s a hands-on guide to help you find a tool that actually does what it says it will. We’ll look at everything from high-volume platforms to AI tools that can nail your email copy, so you can finally make a switch and get back to booking meetings.

What are cold email outreach tools?

In simple terms, cold email outreach tools are platforms that automate sending personalized emails to people you don’t know yet. They’re the engine for your sales team, helping you start conversations and generate leads without manually sending every single follow-up. Most of them come with features for sending automated sequences, personalizing emails with things like names and company info, and tracking what’s working and what isn’t.

How I picked the best Instantly alternatives

To make this list actually useful, I had a few ground rules. I wasn’t just looking for the tool with the longest feature list, but the one that best solved the common headaches people have with Instantly.

Here’s what I was looking for:

• Honest pricing: No hidden fees or confusing add-ons that inflate the price. I wanted tools with clear pricing so you know what you’re paying for from day one.

• Good deliverability: Your emails need to land in the inbox, period. I leaned towards platforms that care about sender reputation, have stable performance, and include features designed to keep you out of the spam folder.

• The right features: A decent CRM, helpful analytics, and solid automation should be part of the package, not locked behind the most expensive plan.

• Easy to use: You shouldn’t need a computer science degree to launch a campaign. I picked tools with intuitive designs that let you get going quickly.

• Support that actually helps: When something goes wrong, you need a support team that can do more than just send you a link to a help doc. I looked for platforms known for being responsive and helpful.

The 7 best Instantly alternatives for 2025

Alright, let’s get into the details. Here’s a closer look at each tool, why it’s on this list, and who it’s really for.

1. eesel AI

Let’s be real, a huge part of cold outreach is the copy. If your emails sound like they were written by a robot, they’ll get deleted. While Instantly dangles AI features, they often produce generic text that anyone can spot a mile away. This is where a specialized tool like eesel AI’s Email Writer comes in. It’s not another sending platform; it’s a dedicated AI writing assistant designed to perfect your messaging.

A screenshot showing the eesel AI Email Writer drafting a personalized email directly within a messaging platform, highlighting one of the best Instantly alternatives.:

It fixes the core problem of personalization by training on your company’s actual knowledge, from past successful sales emails to help desk tickets and internal docs. It learns your brand voice, understands your product, and helps you draft emails that feel genuinely human. Instead of just plugging in {firstName}, it helps you write messages that actually connect with people. You can hook it up to your knowledge sources like Google Docs or Slack and have it running in a few minutes.

Pros:

• Genuinely personalized AI that learns your unique voice and messaging.

• Pulls knowledge from all your company documents, not just generic templates.

• Clear, predictable pricing based on usage.

• You can set it up yourself in minutes without having to talk to a salesperson.

Cons:

• It’s a specialized email writing tool, not an all-in-one sending platform. You’ll need to pair it with one of the other senders on this list.

Pricing:

eesel AI’s plans include all its products, from the AI Email Writer to its AI agents.

• Team Plan: $299/month ($239/month annually) for up to 1,000 AI interactions.

• Business Plan: $799/month ($639/month annually) for up to 3,000 AI interactions and adds features like training on past tickets.

• Custom: For unlimited interactions and more advanced features.

2. Smartlead.ai

If your biggest frustration with Instantly is watching your open rates plummet as emails go straight to spam, then Smartlead.ai is the direct competitor you should be looking at. It’s built for one thing: sending a ton of emails that actually land in the inbox.

Smartlead really delivers with its unlimited email accounts and a master inbox that lets you manage all your replies in one place. Its main strength is a deep focus on deliverability, with features like advanced IP rotation and a solid warm-up process. This directly tackles the "disconnecting accounts" and terrible reply rates a lot of Instantly users complain about. For anyone who needs to scale their outreach, Smartlead has the power you need without the deliverability nightmares.

Pros:

• Great for sending high-volume campaigns.

• Unlimited sending accounts and warm-up are included in all plans.

• The master inbox makes it much easier to manage replies.

Cons:

• Some people find the user interface a bit clunky and not as polished as other tools.

• The agency model costs an extra $29/month for every client you add.

Pricing:

• Basic Plan: $39/month for 2,000 active leads and 6,000 emails/month.

Annual plans give you a discount.

3. Saleshandy

Is Instantly’s pricing punishing you for growing? Having to buy separate workspaces for each client can make your costs spiral. Saleshandy is the solution to that problem. It’s built for agencies and teams that need predictable, affordable pricing as they grow.

Saleshandy’s best feature is that it offers unlimited client and team member management at no extra cost on its higher plans. That alone makes it a much better investment than Instantly. You get unlimited email accounts, a generous sending volume, and a pricing structure that won’t give you a heart attack at the end of the month. It’s made for scaling, without the financial penalties.

Pros:

• No extra cost for adding clients or team members on most plans.

• Very cost-effective with straightforward pricing.

4. Lemlist

If you feel like your plain-text emails from Instantly are getting lost in a sea of other plain-text emails, Lemlist is where you can get creative. While Instantly is all about quantity, Lemlist is about quality and engagement. It’s for sales teams who want to create memorable touchpoints, not just send another email blast.

Its coolest feature is the ability to add personalized images, videos, and custom landing pages right into your emails. Think about sending an email with a screenshot of the prospect’s website with their name written on it, or a quick video where you greet them by name. This kind of personalization can seriously boost reply rates, especially for high-value accounts.

Pros:

• Cool personalization features with dynamic images and videos.

• Includes other outreach steps like LinkedIn actions and cold calls.

• The visual campaign builder is easy and intuitive to use.

Cons:

• Multichannel Expert: $79/user/month (billed annually) adds LinkedIn and call steps, with 5 sending emails per user.

• Enterprise: Custom pricing for teams of 5 or more.

5. Woodpecker

Tired of Instantly’s bugs and general flakiness? Woodpecker is the dependable tool you’ve been searching for. It doesn’t try to be everything to everyone; it focuses on doing one thing really well: sending cold emails that reliably end up in the inbox.

Woodpecker is known for its clean, user-friendly design and its strong reputation for deliverability. It’s a welcome change for anyone who is just fed up with technical problems and wants a tool that works like it’s supposed to.

Annual plans offer a 33% discount.

6. Reply.io

If you feel like you’ve hit the limits of Instantly’s email-only approach, it might be time for a full sales engagement platform. Reply.io is built for modern sales teams who understand that their prospects are on LinkedIn and the phone, not just sitting in their inbox.

Reply.io lets you create coordinated sequences that weave together email, LinkedIn messages, SMS, and phone calls. It’s a much more complete platform for managing your entire sales pipeline in one place. If you’re ready to move beyond just sending emails and start building a real, multichannel sales strategy, Reply.io has you covered.

Pros:

• Full multichannel outreach (email, LinkedIn, SMS, calls).

• Helpful AI features for personalizing emails and handling responses.

• Strong analytics to track your performance across every channel.

Cons:

• The sheer number of features can be a lot to take in for beginners.

Pricing:

Reply.io has complex, usage-based pricing.

• Email Volume Plan: Starts at $59/month for 1,000 active contacts.

7. Salesforge

For the pros who know that deliverability is everything, Salesforge offers a level of control that Instantly just doesn’t have. One of the biggest hidden issues with platforms like Instantly is that you’re sending from shared IP addresses. If another user on your IP acts like a spammer, your reputation can get dragged down with them.

Salesforge fixes this by giving you a complete outreach stack, including options for your own private, pre-warmed sending infrastructure. It’s a solution for teams and agencies who know that long-term cold email success means owning your reputation, not renting it. It’s more than just a sending tool; it’s an entire outreach engine.

Pros:

• Gives you full control over your sending infrastructure.

• An all-in-one platform that covers everything from finding leads to managing replies.

• Offers an optional AI SDR agent for full automation.

Cons:

• The advanced features are probably overkill for beginners or teams just getting started with cold outreach.

Pricing:

• Pro Plan: $40/month for 1,000 active contacts and 5,000 emails/month.

• Growth Plan: $80/month for 10,000 active contacts and 50,000 emails/month, plus unlimited LinkedIn senders.

• Agent Frank (AI SDR): Starts at $416/month for a fully automated agent.

Beyond the platform: 3 tips for better cold outreach

Switching tools is a great start, but don’t forget that the platform is only half the equation. Your success really comes down to your strategy.

1. Your email copy is king. A generic, self-serving template will be ignored, no matter how good your sending tool is. Your message has to be short, relevant, and focused on solving a problem for your prospect. This is where AI that actually understands your business, like the eesel AI Email Writer, can give you a huge leg up by drafting high-quality, personalized emails that sound like you wrote them yourself.

2. Obsess over deliverability. You could write the greatest email in history, but it’s worthless if it lands in the spam folder. Always verify your email lists, set up your technical records properly (SPF, DKIM, DMARC), and warm up your accounts by sending emails slowly at first. Don’t go from sending 10 emails a day to 1,000 overnight.

3. Never stop testing. Good outreach is all about experimenting. A/B test everything: your subject lines, your calls-to-action, your email body, even what time you send your emails. Use the analytics in whatever platform you choose to see what works, ditch what doesn’t, and do more of what’s getting you replies.

Final verdict: How to choose the best Instantly alternative

Moving on from Instantly is all about picking a tool that solves your biggest problem, whether that’s deliverability, unpredictable costs, clunky software, or a lack of control. There’s no single "best" alternative, just the one that’s the best fit for your business.

To sum it up:

• For pure sending power and top-notch deliverability, take a look at Smartlead.ai.

• For agencies that need to scale without breaking the bank, Saleshandy is a fantastic value.

• For creative, personalized emails that get noticed, choose Lemlist.

• For rock-solid simplicity and reliability, go with Woodpecker.

And remember, the best sending platform in the world is even better when you feed it great content that gets replies.
