Pros & Cons
Kit
Pros
- The Free plan allows up to 10,000 subscribers with unlimited broadcasts, forms and landing pages, which is generous for creators who are starting out.
- Built-in sales of digital products and paid subscriptions let creators sell without a separate storefront tool.
- The visual automation builder and sequences on paid plans are easy for solo creators to set up.
- The recommendations network and Pro's referral system help newsletter writers gain subscribers.
Cons
- Third-party reviews report a roughly 35% price rise in late 2025, and costs climb steeply as the list grows. Creator is about $199 a month at 25,000 subscribers.
- Users complain about automatic tier upgrades when lists grow and about paying for inactive subscribers.
- Email templates are fairly plain, and there is no CRM or sales pipeline.
- Free-plan users have no automations and get email-only support. Some Trustpilot reviewers also report poor support responsiveness.
MailerSend
Pros
- Developers can send through a REST API or an SMTP relay, with SDKs and connectors for Laravel, Django, Rails, Symfony, Supabase and Firebase.
- A free tier of 500 emails and a $7 Hobby plan make it cheap to start.
- Capterra reviewers repeatedly praise its responsive support and clear documentation.
- Built-in blocklist and DMARC monitoring help teams protect deliverability.
- Starter and higher plans add an SMS API, and a WhatsApp add-on is available.
Cons
- It is built for transactional email, not full marketing campaign management.
- Reviewers report sudden throttling or account suspensions after bounce or complaint thresholds are crossed.
- Free and Hobby plans keep only one day of activity history.
- SMS is limited to the USA and Canada.
