Smartlead.ai Reviews 

Horrible experience with SmartLead support team. Experiencing multiple bugs, and the support looks like it is AI run, because they ask the same questions over and over of which have already been answered in previous tickets. As of today, the issue is still unresolved. Errors everywhere.

Shady business practices about cancelling and pausing subscriptions. Do not trust them, do not use them.

I have been using Smartlead for many years and it continues to remain one of my main go-to cold email tools both for my own campaigns and for my client campaigns.

I am also consistently impressed by how friendly and communicative the Smartlead team is, especially when you need help.

Probably the worst cold email provider on the planet. I had cancelled my subscription, but as it turns out you actually have to delete your email accounts in order to stop the invoicing. I will also state that I did not recieve one invoice notification. Being paying these crooks for months now. No apology. Just some terms and conditions sent to me. Poor service. Don't waste your time.

We use Smartlead to run cold email for our clients and it's been a great experience overall. Deliverability and inbox rotation just work - that's the thing I worried about most switching platforms and it hasn't been an issue. Support has been genuinely responsive whenever I've needed help, which matters a lot when you're managing multiple client accounts and can't afford downtime. It integrates cleanly with Clay too, so it fits right into how we already build our lists. Pricing is solid for what you get, especially running it at agency volume. Would recommend to anyone doing cold outreach for clients.

good, but not very good experience

If you rely on cold outbound to generate revenue, Smartlead is your best bet for distribution! Especially for GTM Agencies!

Have been using them for over a year now. Good to see they have evolved from email only to complete outbound by adding call as an option which is exactly what my team was looking for. We don’t have to switch b/w tools anymore and use onlysmartlead for both. Platform grows on you and support has been actively addressing any issues. Their AI tools are pretty good and unlike anything we have seen. Good product.

We’ve used Smartlead as part of our outbound work. It makes managing inboxes, campaigns and replies across multiple accounts straightforward.
The API is flexible and integrates well with the rest of our GTM systems. It is a strong platform for serious outbound teams that need reliability and scale without unnecessary complexity.

We've been using Smartlead for our outbound campaigns, and it's become one of the core tools in our workflow.

The platform makes it easy to manage multiple mailboxes, automate follow-ups, and keep campaigns organized without adding unnecessary complexity. It has saved us a lot of time and made scaling outbound much more manageable.

What I appreciate most is how straightforward the platform is. The interface is easy to navigate, campaigns are simple to set up, and the team continues to improve the product with new features.

If you're serious about cold email and want a platform that's reliable, scalable, and easy to use, I highly recommend Smartlead.

it seem to a good fit for our business. However the setup was complex and convoluted. DNS wouldn't recognise, then when came to buying mailboxes payments was made but payment showed failed on there system. When you contact support you get a bot. It then takes between 2 hrs to 10 hrs to get a response from support which is a staller to say there looking at it. You can't get refunds apperently on Smartsenders you can't get a straight answer on anything. I have asked for a full refund as its absolute waste of time and money/

After almost a year of good service they have lost the plot. First, there was an UI bug inside of Smartlead that deleted all my vendor bought emailadresses.

After some back and forth with support, they reinstated my accounts and everything was fine - I lost some days of cold email but at least i was able to start again.

Than out of nowhere the fix they applied still broke and all of my vendor bought (zapmail - I used their system) emails disconnected.

For some reason supports first answer is '' we will enable warmup'' even if you tell them all your emailadresses are disconnected.

This time support has been really slow. I have needed to follow up myself and after 48 hours of them saying ''I escalated it to another team'' I am honestly done waiting and done paying money (almost 200 euro a month) for a setup that breaks, by their mistakes and by their design.

Double charged me and slwo repsonse time to fix it, charge dme and did not get me any of the emails

I've used smartlead for about a year now, it's a great platform.
Whenever I've had any issues at all, the team have been helpful and supportive throughout.
I really can't fault their customer service, it's exceptional, and if you're looking for an outreach tool then look no further than the Smartlead team!

I wish I read these reviews before signing up. STAY AWAY. Bait and switch con artists. After signing up for the free trial, a banner/pop up came on the screen for 3 days offering 50% off the first month. SO, $94 showed $47.
After I signed up, the banner went away and they invoiced me for the full $94 and went on to claim they never offered a promo.

I'm disputing this on my credit card and cancelling. I recommend everyone to stay away.

Do NOT buy the done-for-you email accounts. I bought 45 accounts and shortly after I started sending volume, I got crazy sender bounces. Turns out their "vendor" forgot to setup DMARC and now my accounts are trashed. They provide no replacements or refunds claiming it's an "edge case" and it's my loss. Not a good experience.

We run a B2B lead gen agency and used Smartlead as the email sequencer across many client campaigns. Three honest sentences on why we are migrating away from this platform.

The software does a lot, but not the things that actually matter.

Smartlead keeps shipping new features – dashboards, integrations, AI add-ons – while the core sending and event infrastructure that B2B agencies actually depend on stays unreliable. We have hit issues with webhook delivery (entire event streams silently dropped from production sequences), inconsistent UI behavior in their Smart Infra module (the campaign view contradicts the overview, the inspector flips between views on its own), and recurring deliverability incidents. None of these are exotic edge cases. They are the basic functionality you pay for.

The support is the worst I have encountered in any B2B SaaS tool we use.

Replies arrive on a multi-day cadence even when production data is broken. "I'll check with the team" responses loop endlessly without an engineering touchpoint. When engineering finally does respond, the analysis contradicts itself within the same paragraph, references the wrong customer's configuration as the root cause, and ignores diagnostic information already provided in the thread. Direct questions get sidestepped. Issues raised early in a thread get ignored across a dozen consecutive replies. Compensation offers do not come close to reflecting the operational damage caused.

We spent more time diagnosing Smartlead bugs and writing manual backfill workflows for missing data than we ever did building campaigns on the platform.

If you are evaluating Smartlead for serious B2B use where data integrity and support responsiveness matter: look elsewhere. The marketing is polished, the feature list is long, and the actual product and support experience does not match either. Bugs happen everywhere – that is not the issue. The issue is how Smartlead responds when something breaks, which is: slowly, incoherently, and without ownership.

We are migrating to another platform. The decision was made not because of one bug, but because of what the response to that bug revealed about how this company operates.

One of the best tools I've been using for email outreach for the last 3 years :)

Best cold email platform in the game.

We run Danish Lead Co, a B2B outbound agency, entirely on Smartlead across 110+ client accounts. The unified master inbox, deliverability tooling, and open API are what let us operate at scale, we have built our whole internal ops platform on top of the Smartlead API. Across our clients we have booked 10,000+ qualified meetings using it. Support is responsive and the product ships fast. For any agency running cold email as a system rather than one-off campaigns, this is the tool.
