Director of Communications

I cannot scroll down on my MacBook to see the complete screen material.   And though there are quite a bit more templates, they are very basic visually.  

Project Manager

Highly recommended for businesses seeking efficiency and scalability in their email marketing operations.

Sales Manager

I didn't like anything because when I asked a question to customer service, [sensitive content hidden] who works in Turkey, insulted me and threatened me, so I do not recommend this company to anyone.

Overtime it became possible to use it, but still it has "gremlins."  

Developer

The fact that Inbox's servers are located in Turkey and thus compliant with KVKK was an important factor for us.

director

I use UseInbox as an email client which helps my business manage email communication and marketing campaign more effectively.

I purchased this product awhile ago and just did not use it.  

CEO 

At the moment I have not been able to integrate with woocommerce for abandoned cart campaigns

The automation part is not working properly.

manager

I would like to have more filters in the automations and more templates in the future, but I see that their Road Map is quite interesting.

Web Developer

I really like the Landing Pages section, which is easy to customize and implement, as well the newsletter setup, and the automation section.

What makes useinbox stand head and shoulders over other players that i've used is their dedication to providing helpful and fast support.

marketing and export manager

convention in using, not complicated to understand how to use, capability of sending emails to many persons no matter what, separating the dead mailboxes from adding rights and not counting the repeated ones.

Founder

Actually, the only thing that limited us at the beginning was not being able to use our hotmail to configure it and we had to make an institutional one, which finally made us look more professional hehe.

Architect

I have been using INBOX for my monthly newsletters for almost 12 months now and love it.

I was looking for an alternative solution of Mailchimp and came across useINBOX.

I am not an advanced user, so the software is adequate for my use case

Psychologist

A repository to build our lists off of landing pages, blog posts and to create automation sequences for newsletters, etc.

Director

I would like to be able to use webhooks, this is on the roadmap and am looking forward to this feature to integrate with my other tools.

Coach & Virtual Events Strategist

I wish there were more native integrations with other tools (eg lead capture forms).

Manager

You can manage every mailing operation of your company from just one portal

only thing is missing and that is capability of putting videos in template.

Prophet 

I do not like that there is no CNAME It could be better if they could give us that option of CNAME. and the lack of polish language.

Secretary General

I am writing the feedback because of foreign language problem but we fulfilled the survey with my colleague, [SENSITIVE CONTENT HIDDEN] (ARMATUR Corporate Communications & Administrative Affairs Responsible) who helped in the selection and purchasing processes of this product, who is the administrator and the main user of this software in our association.

Customer Support

I personally would like to see a seemless integration of these tools rather than different things on different subdomains, but that's just my personal pet peeve.

URLS for each section take you to different subdomains and it's hard to get back.

Thirdly, we make serious problems to use numbering, bullets, bold, italic type of writing styles, fonts, line spacing and etc.

Founder & CEO

So far no downpoint I can think of. But if they provide to increase the subscriber count for onetime payment, that will be great.

The price I have paid for 30K subscribers lifetime is just fraction what will cost you for each campaign.

I like the fact that in one place I have form, landing pages, list, and the platform is easy to navigate.

I like the ease of use, the features as well as the ability to handle multiple email accounts in the same application.

Marketing

I am able ot plan much more easily a full campaign set for clients, at a much lower cost than Mailchimp with all the features we need, at a much lower price.

I can see this company grow and improve this product to perfection and becoming a known competitor to bigger brands.

Real Estate Marketing and Sales

I just lost touch after the funnel ended and this gave me the perfect set-up to revisit them with eye-catching photos of what they initially were interested in to see if they click and still have an interest so I can reach out to them further.  

I strongly recommend that you have people do onboarding in front of you so you can see what's not clear, what's confusing and what might be handy.

Engineer

sometimes it loading and have no plugin with website

It is my 5th month working at ARMATUR Association and I clearly see its deficiencies as I worked at TIAD and AIMSAD associations in the past and used different software which were more efficient. If I were here at the time of purchase, I would most probably not select or purchase this product.

Easy to use and works perfectly all the time.

The fact that you can use it for multiple businesses is just great.

Software Engineer

I can create my contact list separately and send an e-mail to the whole list with one click.

Geschäftsführer

I basically will never know when some reports our emails as spam.

The templates are handy for those who don't have an established design but, in my case, I use a homemade design and it works just as well.

Head of Growth

It is not something I don't like but they can add some machine learning tools such as sending frequency optimization or LTV prediction.

It could be a bit more economic or have a some different options

Owner

The newsletter and payment functions make this tool great to close quick deals without needing to interact with the client

Inbox offers a similarly easy and friendly user experience of managing list and creating newsletters with drop & drag approach.

Software is lacking on user experience elements.

The platform acts as a central hub that helps organize outreach efforts more easily, allowing our team to eliminate manual, repetitive tasks and stay highly productive every day.

What was once a manual, time-intensive bottleneck is now an automated machine that constantly feeds the pipeline with high-intent prospects, directly freeing up our team to focus their energy on closing revenue.

The platforms creates a sense of consistency I no longer worry about emails bouncing or losing of replies It allows me to focus on building reationships instead os technicaldetails

Copywriter

I especially found the AI email writer helpful for speeding up my cold email creation—saving me time while still giving me a good foundation to edit. Plus, having everything in one dashboard (CRM, inbox, warm-up, writing) makes the workflow smooth and less stressful.

Equity Trader

The best thing i experienced about this platform, Success AI or any successful AI platform is how it amplifies human potential. Whether it's automating tedious tasks, unlocking deeper insights from data, or helping creators like Me scale contents across platforms, AI becomes a force multiplier.

Website Designer

Emails often land in spam or promotions folders, and the platform doesn’t provide enough insight, guidance, or tools to help improve deliverability or understand the causes behind it.

Admin

Overall success.ai helps me grow my online shop systematically by making it easier to find and connect with potential resellers while allowing me to focus on managing orders and inventory efficiently

Digital Marketing Specialist

It feels like a well thought out tool built for people who want efficency and measureable results. While there is room for improvement, especially in onboarding, the platform delivers strong value and has clear potential for long term use

Design Graphics

Success.ai is a powerful outreach tool, especially for businesses or individuals looking to scale their cold email efforts efficiently. If you're patient with the learning curve and choose the right pricing plan, it can become a central part of your marketing or sales stack.

Technical Support

Some users report that core features stop working for periods (for example, the “Lead Finder” not respecting keyword filters or ignoring certain lead criteria).

marketing manager

I used Success.ai mainly for B2B outreach to generate qualified leads and start conversations with companies that match our ICP.

With the automation and AI suggestions, I’m able to scale campaigns faster and get better response rates without hiring additional people.

With its lead scoring capabilities, it enhances lead qualification accuracy, ensuring that sales efforts are focused on the most promising leads

What I liked least was that some lead data and email personalization still needed manual cleanup, and the UI could feel a bit overwhelming at first for new users.

Virtual Assistant

Useful tool for VA to handling outreach and lead generation, especially for clients who needs scalable cold email campaigns.

founder

It synchronizes data effortlessly, ensuring that we never miss a beat when it comes to tracking our prospects and their interactions with us.

SEO Analyst

The help documentation for creating truly custom user roles and permissions could be more detailed for managers.

Intern

It helps me a lot in the process of avoiding gaps in my outreach and keeps sales activity moving without delays.

Head of Human Resource

A feature I found useful is the precise filtering that allows me to target by location and industry.

Supervisor

I think the dashboard could offer more visual reports and charts for better tracking of campaign progress.

This saves me time, increases my productivity, and helps me focus more on writing high-converting emails rather than wasting energy on manual prospecting.

Digital Marketing

The platform is easy to use and genuinely helpful for creating more personalized and effective email campaigns, which made my workflow smoother and more confident. While the initial setup took some adjustment and there were a few minor glitches, they didn’t outweigh the benefits, and I’d still recommend Success.ai to others looking for a practical email marketing tool.

Accounting

It helps to identify the right leads to target, also personalize emails, and keep record the results of campaigns for future strategy

Maketing

The best part about using success.ai for lead generation is how it combine data, automation, and personalization into single platform.

The combination AI and a vast contact database made it easier for me to reach out potential clients and expand my network effectively.

Co-founder and CEO

This software connect my lead generation efforts with my sales process, ensuring a smooth transition from lead to customer.

It has a ready-to-use template to make my work feel easier, and the UI/UX is so simple to use for a beginner like me

The design could use more color like contrast to make navigation a bit easier on the eyes. but still 100% for me.

Recruitment specialist

Success.ai offers the ability to send unlimited emails, breaking free from constraints and allowing businesses like mine to elevate their campaigns with unparalleled engagement and conversions.
