What Users Say

Reviews from Trustpilot, linked to the source

Trustpilot

“I've just switched to ActiveCampaign and can't believe how it handles content management, email sequences, and a whole lot of other sophisticated features. The learning curve is a bit steeper than with some other options, but the personal onboarding support was a huge help.”

Michael HawkerView on Trustpilot
Trustpilot

“I signed up for AC and had to wait a week before I could get an integration/onboarding call. I emailed the salesperson who signed me up twice and then left him a voicemail the next day to see if he could help me get a few questions answered so I wouldn't have to wait a week. Guy ghosted me.”

Use-case matchups

Situation Best first look Why
Privacy-first team wants open-source newsletter infrastructure Keila Keila gives more control over hosting, data location, and source code.
Marketing team needs advanced automation and CRM ActiveCampaign ActiveCampaign is built for complex journeys, scoring, CRM, and sales/marketing workflows.
Technical team can self-host and only needs email basics Keila The low price works best when the team accepts infrastructure ownership and lighter automation.
Team wants managed automation without server work ActiveCampaign It removes hosting work and provides more mature automation out of the box.
SaaS team needs Stripe-aware lifecycle email Sequenzy Sequenzy is focused on billing and product-triggered email rather than general CRM automation.

Pricing reality

Keila's $8-32/month cloud pricing is low, and self-hosting can reduce software cost further. The real cost is operational: hosting, sending provider, DNS, backups, upgrades, deliverability monitoring, and technical ownership.

ActiveCampaign's $79/month comparison point buys managed automation and CRM features. Confirm contact tier, required plan, CRM access, predictive features, support, and any onboarding or add-on costs before comparing it to self-hosted software.

Sequenzy's $49/month price is only the right comparison when the job is SaaS lifecycle, transactional email, Stripe events, and campaigns rather than open-source control or full CRM automation.

Review signals

Platform What reviews in this page suggest What to validate
Keila Review themes favor open source, EU hosting, self-hosting, GDPR control, and reliable newsletters. Confirm infrastructure ownership, integration limits, and automation depth.
ActiveCampaign Review themes favor stronger managed email marketing, automation, CRM, and easier setup than self-hosting. Confirm pricing at your contact count, CRM requirements, support expectations, and migration effort.

Best Fit by Control and Complexity

Best open-source email platform for privacy-focused newsletters

Keila fits teams that want open-source software, EU-friendly hosting options, and simple newsletter or campaign sending with more data ownership. It is strongest when privacy and control matter more than advanced CRM automation.

Best marketing automation platform for CRM-driven growth

ActiveCampaign is the better fit when the team needs lead scoring, branching automations, CRM pipelines, sales follow-up, and broad integrations. It is easier to justify when automation depth creates more value than open-source ownership.

Best SaaS lifecycle platform for managed event-based email

Sequenzy fits SaaS teams that want product-triggered and billing-triggered email without self-hosting or building automations from scratch. It is a stronger fit when lifecycle workflows need revenue context but the team still wants a managed product.

Migration checklist

Workstream Moving toward Keila Moving toward ActiveCampaign Moving toward Sequenzy
Infrastructure Decide cloud vs self-hosted, SMTP provider, DNS, backups, updates, and monitoring. Configure domain authentication, account permissions, tracking, and integrations. Configure sending domains, Stripe, app events, and transactional routes.
Contacts Export contacts, lists, tags, custom fields, consent, and suppressions. Import contacts, tags, lists, fields, deals, scores, and suppressions. Import subscribers, attributes, tags, suppressions, and billing identifiers.
Automations Keep flows simple or plan external automation around Keila. Rebuild journeys, scoring, CRM tasks, deal updates, and nurture sequences. Rebuild trial, onboarding, upgrade, dunning, transactional, and product-triggered flows.
Templates Recreate newsletters and MJML/editor templates. Recreate campaigns, forms, automations, and personalization fields. Recreate lifecycle and transactional templates.
Reporting Define newsletter performance and deliverability checks. Define campaign, automation, CRM, revenue, and lead-scoring reports. Define lifecycle, billing, transactional, and campaign reporting.

Decision checklist

  • Is open-source control more important than mature automation?
  • Who owns hosting, updates, and deliverability if you choose Keila?
  • Does ActiveCampaign's CRM and scoring replace tools you already use?
  • Do you need SaaS billing events more than generic marketing automation?
  • Which platform can your team operate cleanly six months after migration?

Open-Source vs Commercial Trade-off

Keila's AGPLv3 license means the source code is yours to read, run, and modify, including self-hosting on your own servers with no vendor tie. ActiveCampaign is closed, commercial software: you pay for access to its 850+ automation recipes and built-in CRM, and that access can change terms or price at any time. Keila trades some of ActiveCampaign's polish for that independence.

EU Data Sovereignty

Where subscriber data physically lives differs between the two. Self-hosted Keila keeps every record on infrastructure you control, and Keila's cloud option runs in the EU for teams that want GDPR-aligned hosting without managing servers. ActiveCampaign stores your contacts on its own infrastructure, which is fine for most teams but means you're relying on their jurisdiction and policies rather than choosing your own.

The Self-Hosting Reality

Running Keila yourself means owning the server, the updates, and the backups, which only makes sense with some DevOps capacity on the team. ActiveCampaign's $79-a-month plan removes that burden entirely along with giving you its CRM and lead scoring. Teams without infrastructure staff will generally get more done faster on ActiveCampaign's managed service than on a self-hosted Keila instance.

Founder, LandingBoost

It’s the first tool where I’m actually willing to keep working on email without it turning into one giant scary blast. Favorite part is still what I said, being able to split stuff. Drafts vs campaigns vs a single-person send. I can park a lot of “don’t send this yet” work with labels and not feel like it’s one click away from going to everyone. Sequences later. Consent / lists first. I’m slow on purpose.

We used Sequenzy to replace a generic onboarding flow with coordinated lifecycle journeys covering signup, connecting Google Search Console, discovering SEO opportunities, upgrading, and paid-customer retention. Event triggers, conditional branches, personalization, and enrollment cancellation gave us precise control over who receives each message - and when someone should exit a journey. We backfilled eligible users into the appropriate journeys. The initial emails went out without bounces, complaints, suppressions, or unexpected recipients. Future users now enter the relevant journeys automatically based on their activity in CrawlRaven.

Codex basically one-shotted the migration for syncing our audience from SendGrid to Sequenzy. Sequenzy is fully observable, so agents can just set everything up. The net impact is saving $45/mo, plus 2 hours of my time every time I need to repurpose a newsletter. That's 8 hours a month. My consulting rate is $550/hr, so every hour automated is super valuable.

Solo founder, Moxie Docs

Lifecycle email was the kind of thing I knew I would need eventually, but have never had to build it out myself and had no idea where to start. In literal hours I had a fully working (but basic) flow for onboarding new users, detecting churn, and re-engaging people who have trials lapsing to hopefully convert. Sequenzy let me offload the entire “keep users engaged and recover the ones who are slipping” workflow to something that just runs. Every hour I'd have spent building and babysitting lifecycle emails went into shipping the actual product instead.

Loving the Sequenzy app so far due to the affordability and large subscriber limits. Planning on this becoming my main email app. Campaign + flows setup with the help of their AI took less than 30 minutes.

I've used 2 other email marketing tools. They were supposedly "market leaders". Both were clunky, unnecessarily expensive and horrible support. When I tried Sequenzy I thought there'd be trade-offs compared to the others. But there weren't, it had everything I needed, there was no bloat, emails delivered extremely fast, and the founders shipped anything I asked in a day. The best part is that Sequenzy is AI native, I rarely do stuff in the dashboard, just use my AI to create campaigns, sequences and segment customers which saves me a ton of time. Never been happier with an email marketing tool.

$600 revenue in 30d from email automations. Very happy I migrated to Sequenzy. Before I was making zero from email automations.

Sequenzy's most powerful feature is probably those campaigns. It seems useless at first but they are one of the most important things to send to your users. I get to talk to my users 1:1 and help them set it up for their use case. The owner is really active on X, really nice and helpful. He's the type of person to go out of his way to help you, so you get really good support!

After using Loops and Resend, I was looking for an email infrastructure service that had MCP support, Affonso and Dodo Payments integrations, and was affordable. Came across Sequenzy, and the support from Nic has been unbelievable. Migration was done in 24 hours without any issues, and I can run all of my products from a single account.

Jim

I run a SaaS, and found Nic on X where I kept seeing posts about his email marketing tool, Sequenzy. I decided to try it for email marketing. Literally on the first day, I used it to send a marketing campaign and I got 5 sales. What I like most is the ai assistant because it actually writes emails that feel real instead of the usual ai slop chatgpt returns, so they do not end up in spam. It also has a 2.5k free email limit which is way better than most tools that only give you around 1k. The best part though is that it handles everything for me, tags, subscribers, sequences and all of it. Without it i would probably be managing a database and a bunch of cron jobs just to make email automation work. Sequenzy just makes my life a lot easier. it can also be set up with 2-3 clicks! Give it a try!!
