"Powerful cold outreach tool with seamless API integration"
4.5/5
What do you like best about Mailshake?

What I like best about Mailshake is how straightforward it is to build and manage email sequences. No bloated interface, no unnecessary complexity. As an agency owner running cold outreach for clients, I need a tool that just works without a steep learning curve.

The full traceability across every sequence is what really stands out. I can see exactly when a lead was won, who is up next, and where every single contact stands in the pipeline at any given moment. That visibility alone saves a massive amount of time.

On top of that, the API integrations are genuinely impressive. Connecting Mailshake with our existing tech stack was seamless and opens up a lot of automation possibilities that most tools in this space just don't offer as cleanly. Review collected by and hosted on G2.com.

What do you dislike about Mailshake?

The only thing that mildly bothered me was that emails had to be set up separately within the sequences. There is no native way to duplicate or clone them easily, which adds unnecessary manual work, especially when running multiple similar campaigns. I ended up solving this through the API to automate the process, but a built-in duplicate function for emails would make the workflow significantly smoother for users who are not as technically inclined.

"MailShake: Easy to Learn, Great In-App AI Support, and Intuitive Analytics"
4.5/5
What do you like best about Mailshake?

What I like about MailShake is it's (1) Quick Learning Curve and Ease of Use - just one day from concept to campaign, (2) Very Good AI Support from withing the App, (3) Quick Email response to questions that AI could not answer (4) Intuitive Analytics to understand the results of a Campaign (5) the fact that Email sends from within by Gmail account. Review collected by and hosted on G2.com.

What do you dislike about Mailshake?

We subscribed to Email Outreach which provides for two email accounts. Would have like at least one more account since a campaign of any meaningful size will go out very slowly with only two email accounts. I can always buy more. Prospects are tied to Campaigns - Would like to be able create campaign lists that can be attached to Campaigns. Would like to be able to download Opens and Clicks individually - I understand that some of this functionality may be available in Sales Engagement module. Review collected by and hosted on G2.com.

"Excellent Email Warm-Up, Powerful Campaign Search, and Great Deliverability"
4.5/5
What do you like best about Mailshake?

We love being able to warm up new email accounts. We also appreciate the breadth and depth of the search function on the Campaign screens and use it daily! Review collected by and hosted on G2.com.

What do you dislike about Mailshake?

We wish Mailshake would maintain the send sequence in the order we enter the campaigns. For example, if we have 3 campaigns sending from the same address, the sequence of assigned sends across the Initial and Follow-up campaign messages gets sloppy and does not seem to correlate to the sequence and send schedule settings we apply.

"Good Campaign Insights and Customization, but a Frustrating Learning Curve"
3.5/5
What do you like best about Mailshake?

There’s good information available on the open and click rates for each sequence and campaign. I can create my own campaigns using my content or start from a template. It’s also easy to customize everything to fit my own process. Review collected by and hosted on G2.com.

What do you dislike about Mailshake?

In full transparency, I’ve only been using Mailshake for a few weeks, so I haven’t had the chance to explore all of its capabilities yet. So far, though, it hasn’t felt very intuitive when I’m starting a new campaign. I’ve spent quite a bit of time trying to understand the UI, more time than I’d prefer, and that has led to some frustration on my part. Review collected by and hosted on G2.com.

"Mailshake Makes Cold Outreach Simple with Intuitive Sequences and Automated Follow-Ups"
4.5/5
What do you like best about Mailshake?

Mailshake makes cold email outreach straightforward for small business owners and entrepreneurs. The sequence builder is intuitive, and being able to upload a prospect CSV and run automated follow-ups saves a ton of time. The campaign wizard walks you through each step clearly. The merge tag system allows for personalized emails at scale without manually editing each one. Great tool for anyone doing supplier outreach or B2B prospecting. Review collected by and hosted on G2.com.

What do you dislike about Mailshake?

The personalization step in the campaign wizard requires you to manually review each prospect individually, which becomes tedious when running larger campaigns. It would be more efficient to have bulk field mapping applied across all prospects at once rather than clicking through them one by one. The pricing also feels steep for newer businesses just getting started with outreach. Review collected by and hosted on G2.com.

"Buggy Platform and Hard-to-Reach Support Undermine the Experience"
1.5/5
What do you like best about Mailshake?

I like that it is made for cold emailing. With other marketing platforms, it can be difficult to send emails out to companies we haven't made contact with previously Review collected by and hosted on G2.com.

What do you dislike about Mailshake?

The platform itself has a lot of bugs and issues. I frequently run into errors, pages that won't load, and parts of the website that won't work. For example, just this morning, I attempted to run the list cleaner option, and I received an error message after 20 minutes of waiting stating that 'the list cleaner is having trouble updating your results.' I cancelled it and tried to re-run it, but it just kept reverting to a message stating that no lists are being cleaned. Also, support is almost non-existent and difficult to reach.

"Unbeatable Value and Easy-to-Use UI with Plenty of Freedom"
4.5/5
What do you like best about Mailshake?

For the price, it cannot be beat. I've used it off and on since 2017 or so and it's gotten even better since then, obviously. There have been a lot of new companies that have come up and they have some cool features, but MailShake is just so much easier to use, while also giving you a lot more freedom. There aren't a lot of upsells like there are in SalesHandy or Instantly, and the UI is fairly simple to use. Review collected by and hosted on G2.com.

What do you dislike about Mailshake?

I can't say there's anything I *dislike*, aside from the price -- yet even that is cheaper than the competition, so I can't think of any real issues. Review collected by and hosted on G2.com.

"Easy Cold Email Outreach and a Handy Lead Finder"
4/5

I like how easy and straightforward the cold email approach is, and I also enjoy the lead finder feature. Review collected by and hosted on G2.com.

What do you dislike about Mailshake?

Not much to add, really, but I do think it could improve the number of mailboxes you get for the price. Review collected by and hosted on G2.com.

"Powerful Reporting and Team Setup, but Team Switching Can Lag"
4/5
What do you like best about Mailshake?

The list cleaning is super helpful, but I have noticed that if I take the list of "bad" addresses and rerun it, I always end up with some more emails that were deemed "bad" the first time, but are "good" the second time.

The program remembers who has bounced/unsubscribed for you and will not send to those addresses if you accidentally include them in a contact list.

I enjoy all of the different reporting features and views that Mailshake has. It is super easy to check on your campaign health.

With the spread out sending schedule, I enjoy that you can tweak your campaign message while it is still running if you find that something is affecting deliverability, like a poor subject line. Then you have a better chance of reaching inboxes that the blast has not gone to yet.

I like how many different teams we an have. It is super useful for our company, as we serve many different clients and can create a unique team for each of them.

The customer support is excellent. Super friendly and typically quick to respond. They know their products well, and can explain why something happened in addition to helping you fix it.

The different types of campaign that you can build to be launched automatically is super nice. Review collected by and hosted on G2.com.

What do you dislike about Mailshake?

Sometimes it has a lag when you switch teams, and it will bounce you back into the team you are trying to switch away from 2-3 times before you can switch. It is not a bis issue, but a small, reoccurring annoyance.

I wish some features had autofill/remember me capabilities, like when you log in or are sending yourself a test email.

It would be nice if we could edit the footers/signatures with a tab that is in the campaign section. It can be irritating to fully exit a campaign to go to another tab and the click through all the previous campaign set up sections before reaching the design part again.

"Effortless Email Campaigns, Reliable Performance"
4/5
What do you like best about Mailshake?

I like that Mailshake is very convenient to set up for email campaigns compared to other tools I've used, like Smartreach. It's easier to set up, and it works well. Emails sent using Mailshake don't sit in a spam box but actually hit the inbox, which is really important for me. I also appreciate that it only takes about five to ten minutes to set up a campaign if I have my content ready. Review collected by and hosted on G2.com.

What do you dislike about Mailshake?

Sometimes, there are some technical glitches that happen with Mailshake. It's very normal, but those times I feel a little worried. Review collected by and hosted on G2.com.
