lemlist offers a large set of features to control all the process of email outreach.
Also listed in AI Sales Assistant, Email Deliverability, Outbound Call Tracking, Email Marketing

What I like best is how lemlist is built for the AI era. Their MCP server lets me connect lemlist straight to Claude and run campaigns in plain language. I can check stats, build sequences, add leads and tweak settings without clicking through menus. This saves me a lot of time.
The embedded agent is the other big win. It reviews my campaigns and suggests ways to improve them, like better copy, sequence changes and sender setup. It feels like having a campaign expert on call. The results are clear: I spend less time on busywork and more time on strategy.
It’s also easy to use, and the platform keeps getting better. Review collected by and hosted on G2.com.

Also listed in Email Deliverability, Email Template Builder, SMS Marketing, Social Media Management, Event Marketing

I like how easy Constant Contact is to use, and that I can speak with someone if I need help. It lets me communicate with my clients’ audiences in a timely manner, send news, and announce classes. I like designing newsletters and emails with easy-to-use templates, saving my own templates for clients, and uploading images to use in different emails. It’s a valuable tool for my clients to spread their word to their audiences. The initial setup was very easy. Review collected by and hosted on G2.com.

I build websites, and sooner or later every one of them needs a contact form that actually reaches a human. The website is the easy part. Getting the email delivered, rather than having it quietly swallowed by someone’s spam filter, is not. On boher.ie, Brevo’s SMTP relay plugged straight into the standard .NET mail configuration, with no SDK, no custom code and no drama. You point the site at the relay, give it the credentials and it works. That’s the whole review, really, but G2 wants more words.
Verifying the sender domain is clearly explained. For me, that’s the difference between a tool I’d recommend to a client and one I’d quietly replace. Review collected by and hosted on G2.com.

I really like that Intuit Mailchimp Email Marketing is very easy to use. It's simple to make emails look pretty and organize everything, so I can place things wherever I want, and change colors and themes. I also appreciate being able to target specific clients and the auto resend feature that helps increase the email open rate. It tells me who opened the emails and who didn’t, which is super helpful. My clients notice the effort in the emails due to the way I can organize photos, paragraphs, links, and make everything look neat. The setup was straightforward, very self-explanatory and not complicated at all. Review collected by and hosted on G2.com.

Also listed in Email Template Builder, E-Commerce Tools

I love that Flodesk is affordable for small bloggers and content creators. But, it doesn't skimp out on quality. There are so many beautiful templates you can use for your emails. Flodesk is also always trying to add new features to make reaching your audience and managing your list easier. The website itself is really fast and seamless and never slows me down when working. There are a lot of integrations too. I love that they can integrate with my ad network so I can make more money from my emails. Support has always been really helpful. Recently they helped me change my billing date and they were so sweet and nice through the whole process. Review collected by and hosted on G2.com.

Also listed in SMS Marketing, Email Template Builder, Push Notification, Conversational Marketing, Lead Capture

Sender is easy to set up and use, even for a small online shop like ours. We built a signup popup and an embedded form on our website, connected a welcome email with a discount code that goes out automatically, and we can send our own custom HTML newsletters and schedule them in advance. The free plan gives us everything we need to start. The support team is also excellent. When we had a delivery problem with Microsoft addresses, Lucas from the support chat sorted it out the same day and explained everything clearly. Really appreciate the help!

With various recognitions and trust from businesses, MailBluster is the most advanced, reliable, and cost-effective email marketing software in the world. With its Top Perform

MailBluster is an email marketing platform that distinguishes itself through a multi-SMTP architecture, allowing users to connect their own sending infrastructure via Amazon SES, Postmark, Mailgun, or SMTP2GO. This flexibility is a significant technical advantage because it means I am not locked into a single provider. If deliverability or pricing changes with one SMTP service, I can switch or test alternatives without migrating to an entirely new email platform. The recent addition of Postmark, Mailgun, and SMTP2GO as supported providers beyond the original Amazon SES integration demonstrates active development and responsiveness to user needs.
The campaign builder offers both a drag-and-drop email composer and raw HTML editing capabilities. The drag-and-drop editor produces responsive HTML newsletters without requiring any coding knowledge, while the HTML mode gives full control over template structure for more complex designs. I have found the drag-and-drop interface to be intuitive and quick for standard newsletter layouts, with content blocks snapping into place logically and preview rendering accurately across desktop and mobile views.
List segmentation is handled with depth and precision. I can target and retarget subscribers based on behavioral data: who opened or did not open a specific email, who clicked a certain link, or what products they purchased. This level of granularity allows for highly targeted campaigns without needing a separate marketing automation platform. Combined with custom fields and tag-based organization, the segmentation engine provides enough flexibility to build complex audience segments for personalized messaging at scale.
A/B testing is natively supported, allowing me to set up two variations of a campaign and measure which performs better in terms of opens, clicks, or conversions. The implementation is straightforward, and results are clearly displayed so I can make data-driven decisions about subject lines, content, and send times without guesswork.
Real-time tracking and reporting cover all essential metrics: opens, clicks, bounces, complaints, and eCommerce conversions, visualized through charts and data tables. The tracking updates in near real-time, which is critical when monitoring campaign performance during time-sensitive sends. The reporting interface is clean and does not require navigating through multiple screens to find the data I need.
The double opt-in feature is well-implemented and helps build qualified lead lists while maintaining strong sender reputation. This is particularly important when working with SMTP providers that enforce strict complaint rate thresholds, as confirmed subscribers are significantly less likely to mark emails as spam.
The pricing model is remarkably transparent and affordable. The Pro plan costs 60 USD per year plus 0.60 USD per 1,000 emails sent through MailBluster, with the SMTP provider's fees billed separately. For high-volume senders, this structure results in dramatically lower costs compared to traditional per-subscriber pricing models used by competitors. The Starter plan offers a free tier with up to 3,000 emails and unlimited leads, which is generous for testing or very small lists. The Executive plan at 120 USD per year adds dedicated support, 3-year data retention, unlimited automation workflows, and a 5% yearly reward on email sending costs.
The developer API is RESTful and well-documented, supporting programmatic subscriber management, campaign triggering, and event tracking. This makes integration into custom applications, CRMs, or backend systems feasible without depending solely on the dashboard. The ability to mass add, delete, or unsubscribe leads via API or bulk operations is a time-saver when managing large lists that change frequently.
Bounce, complaint, and unsubscribe handling is automated and works seamlessly with the connected SMTP provider's feedback loops. This ensures list hygiene is maintained passively without manual intervention, protecting sender reputation over time.
The platform supports multiple brand users and roles, which is essential for agencies or teams managing email marketing for several brands from a single account. Each brand can have its own configuration, templates, and subscriber lists while being managed under one umbrella. Review collected by and hosted on G2.com.

When we wanted to double check our mailboxes were okay, their support team pulled a bounce report for us, which was nice.
