Excellent Email Warm-Up, Powerful Campaign Search, and Great Deliverability
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.
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.
Mailshake has been the best service we can find when it comes to deliverability and not landing in the recipients' Spam folders!

Early days but lots of potential !!
Only been using Mailshake a few months but can already see the benefit of the system and what it can offer going forward.
Have recently attended a training session which I also found very useful indeed.
Excited for the journey ahead once I become more confident of the features and benefits Mailshake can support me with,

Excellent Deliverability with Built-In Warmup and Super Responsive Support
Switched from Klenty to Mailshake — Huge Improvement in Deliverability ⭐⭐⭐⭐⭐
I was previously using Klenty for cold email outreach, but I was constantly frustrated with poor inbox placement and emails landing in spam. No matter how much I tweaked things, deliverability remained inconsistent, which killed my reply rates.
After switching to Mailshake, the difference has been night and day. My emails are now landing in the inbox far more reliably, and I’m actually seeing conversations start with prospects.
What stands out most:
Excellent Email Deliverability — Mailshake takes deliverability seriously. Between proper warmup, DNS recommendations (SPF/DKIM/DMARC), and real-time monitoring, my sender reputation has improved noticeably. I’m getting way better inbox placement than I ever did with Klenty.
Built-in Email Warmup Tool — This has been a game-changer. It automatically warms up my sending accounts with real interactions (opens, replies, marking as not spam), so I don’t have to babysit the process or use a third-party tool. New domains ramp up safely and quickly.
Super Responsive Support — Whenever I’ve had a question — whether about campaign setup, troubleshooting, or optimizing sequences — the team has been incredibly helpful and fast to respond. They genuinely want you to succeed.
Helpful Educational Resources — Mailshake provides excellent guides, their Cold Email Masterclass, and the Cold Email Academy. These resources cover best practices on copywriting, sending cadence, personalization, and deliverability — super valuable for anyone serious about email marketing.
Overall, Mailshake feels like a more mature and reliable platform for cold outreach. If you’re struggling with deliverability like I was on Klenty, I highly recommend giving Mailshake a try. It’s not just another automation tool — it actually helps you send emails that get read.

Mailshake is easy to use. The dashboards are particularly helpful. I can see at a glance which emails are performing best and see who is engaging the most. It's a good window into how effective my communications are.

Reliable Tool for Streamlined Outreach Campaigns
I’ve been using it regularly for outreach campaigns, and overall, it’s been a reliable tool for managing and scaling email efforts. Setting up sequences is straightforward, and the interface makes it easy to keep track of conversations and follow-ups.

Mailshake has been very useful for outbound email campaigns and day-to-day outreach management
Mailshake has been very useful for managing outreach in a simple and organized way. One of the biggest advantages for me is being able to run multiple campaigns without feeling limited by contacts, which makes it practical when handling ongoing outreach work. The scheduling calendar is also very convenient and makes campaign planning much easier.
The platform is straightforward to use, list cleaning is helpful, and overall it saves time when managing email sequences.
One limitation I noticed is that attaching files directly inside emails would make certain campaigns more flexible, so that is something I would like to see improved.
Overall, it has been a reliable tool for outbound email campaigns and day-to-day outreach management.

Mailshake has been a huge part of our lead generation and outreach success!
Mailshake has been a huge part of our workflow lately.
Simplicity and Speed: I love how intuitive the interface is. I can go from a CSV list to a live campaign in no time, which is essential when I'm managing tight schedules.
Effective Follow-ups: The automated follow-up sequences are a game-changer. Being able to "set and forget" the second rounds while knowing they’ll stop the moment someone replies makes my job so much easier.
Deliverability: We’ve been seeing great results within our account. The platform’s ability to handle plain-text emails properly really helps us stay out of the spam folder and land directly in the inbox.
Real-time Analytics: I love the clear, visual breakdown of the daily performance. Being able to see exactly how many emails were delivered versus opened or bounced at a glance, makes it so much easier to monitor the pulse of our campaigns.
Tracking Engagement: The ability to track unique clicks and opens in a simple chart helps us understand which templates are resonating best with our leads, allowing us to pivot our strategy based on real data.
