Comparing Sendinblue vs. Convertkit

Sendinblue offers advanced email marketing features at highly affordable prices.

Sendinblue vs. Convertkit Pricing

Convertkit pricing is based on the number of subscribers stored. If you’re a blogger or small business with a rapidly growing list, you can expect your email bill to increase significantly over time.

Sendinblue pricing is based on the number of emails sent. You can stored an unlimited number of subscribers (even on the free plan) and this will not affect the overall cost.

Both solutions have a similar starting price but as you can see below, Convertkit quickly becomes a lot more expensive than Sendinblue as your subscriber base grows.

Send a monthly newsletter to: Sendinblue Convertkit
1000 subscribers $25 $29

5,000 subscribers $25 $79
10,000 subscribers $25 $119

Email Design & Testing Features

Sendinblue comes complete with all the email design and coding features you need to create visually stunning emails. You’ll have access to three different editors: Drag & Drop, plain-text, and HTML. Email design is an easy, intuitive process.

Convertkit specializes in plain-text emails, not ideal for any business with lots of product images. There is an option to customize HTML blocks within the plain text email editor but this takes time and requires coding skills.

If coding is your thing, Sendinblue’s WYSIWYG HTML editor lets you view and edit the source code of the entire email so that you can customize it any way you want.

Contact Management & List Building

Both Sendinblue and Convertkit offer unlimited customizable signup forms to which you can attach as many different content upgrades and opt-in incentives as you need.

Convertkit is a subscriber-centric platform so you only have one list, separated using tags and segments.

Sendinblue lets you create multiple distinct lists which some may find easier to organize. Each subscriber has custom contact attributes so you can segment on a granular level and send highly personalized, targeted emails.

Sendinblue’s Multi-list Subscription Form feature helps you stay GDPR compliant by segmenting according to consent for different newsletters, promotions, etc. This way you can be sure subscribers will only receive what they signed up for.

Reporting & Analytics

Convertkit offers basic reports with email open rates, click-through rates, number of unsubscribes and clicks. However, there’s no data available for bounce rates, conversions, or any other detailed statistics.

If you love to deep-dive into data, Sendinblue is the tool for you. Our detailed reporting suite offers all of the above plus extras like the average time to open/click, number of complaints, and lots more.

They explain it best

Fantastic service at a very good price

"At first, I was using Constant Contact to send my press releases, but it cost me 5 times more than what Sendinblue charges me. Now I can send my press releases in a clean, professional manner to radio hosts and producers, as well as news stations and interviewers. The ones who don't want to receive my releases can just unsubscribe, which over time keeps my contact list up to date."

The best newsletter mailing software out there

"My recommendation: Quit using Constant Contact and MailChimp now, and try Sendinblue. You'll save money. Sendinblue helped us build a substantial database of customer contacts without costing us hundreds of dollars every month."

A complete email marketing solution

Sendinblue has really great features and keeps every one of its promises. Personally, the software has helped me send out large email campaigns that are different from the usual business emails. When I send offers to my customer database, I know that my message will go straight to my customers' inboxes, not their spam. I can analyze the links my customers click on to find out which emails have the best conversion rates. I can also send text messages. I use the service at least once a month, because it's really helped me to be there for my customers.
