I use mailjet in daily work and keep in mind if one of the clients asks for advise or recommendation. Mailjet offers and provide so many working services and features that while one implements them there is no time to think about the shortcomings.

1. innovative technologies and features 2. the necessary functions that can be extended and / or scaled if necessary 3. never experienced issues 4. high abvailability 5. API / developers friendly 6. full-stack developer friendly 7. spam filters / precise analytics / statistics 8. free plan and fair pricing 9. intuitive admin web UI 10. documentation and clear tutorials

The Mailjet template creator is easy to use if you have any experience using other template creators. Love how they include "saved sections" in the template creator for ease of creation. Mailjet has strict rules for anti-spam measures and that's a good thing. The majority of my emails do get delivered. For the frequency of our newsletters, Mailjet is perfect for our company. For transactional emails, we use Marsello because of its vast segment properties.

Picking a mail software is extremely stressful since most companies will charge you an arm and a leg when your list grows. Mailjet is the most value-driven software for medium-sized businesses.

If you want to segment at all, you have to upgrade to higher payment tiers. After testing their segment tiers, I wasn't too impressed by the options, so I downgraded it.

Overall, if you want to send a little bit of email with webhooks and api calls, this will work. If you're sending large scale campaigns, it could ruin your email list size because of the lack of functionality around reengagement campaign parameters.

The sales people and customer support were very nice. If you were looking to use the free tier or send low volume of emails then MailJet will do the job (ie: in place of MailChimp) however, if you're looking at this v's constantcontact or sendgrid, selligent etc then I would definitely not go with MailJet.

MailJet do not want clients to use them as a databasing tool which means, if you have a segment of users who are engaged and opened 20 times in the last 30 days and you want to get those email addresses to push into facebook to find a look alike audience...you can't. MailJet won't let you get that data. They also blacklist your softbouncing emails in the background and limit the characters in subject lines.

Integrating Mailjet has been quick and everything worked from the get go

Mailjet is easy and quick to integrate. You can simply create new templates and plug them into you own applications.

The templating language can be hard to master, especially when using complex functions such as loops and conditions.

Ease of use A plethora of features Messages arrive to inbox (not spam) Good analytics Overall value is good

Mailjet limits your sending rate at first Some features could be more customizable (e.g. subscriber forms/widgets) Can be a bit complicated to add sender addresses and verify URLs

Mailjet has all funcionalities needed for sending transactional emails. Great backoffice application and EU based

Transactional confirmation API structure need some manual tricks to work with many domains and subaccount in an efficent way

Overall I left Mailjet. The cost involved was too high. Customer service was not great. The interface was nice but didn't out weight the cons.

Mailjet was a great resource for creating engaging emails. The creative tools for making emails were very easy to use. Creating powerful engaging emails was very quick and the end result was exactly what I was looking for on the creation side of the platform.

So unfortunately I was unable to continue using Mailjet. The cost involved is pretty competitive but still very expensive. I came into some problems with a few of my emails and the customer service was underwhelming. They made things very challenging. I missed a few planned emails with specific deadlines due to not being made aware of the problems going on. Unacceptable. So I switched.

Great DX for the integration, familiar UI, great analytics, honest pricing, possibility to send SMS. The product I was looking for, recommended.

- Easily create email templates with web-based editor - Great analytics for your emails - Easy API integration

- Cannot buy a dedicated IP unless you send 150k emails/month, I'd like to build my reputation from now

Overall they are offering good services in the budget if you want to build and send a newsletter weekly.

Easy to use newsletter builder included, Can test the service a free plan including 6000 mails per month. Can be used as a mail delivery service such as an SMTP.

Required monthly subscription if you are sending more than 6000 emails per month. Somehow costly as compared to other services.

The mass email distribution tool is very dynamic and fast, which greatly facilitates the work of press relations and the like.

It could have more tools in the free version.

MailJet has been a drop in replacement for Madrill. It has been more than adequate for all of my transactional emailing needs.

After using MailJet as a replacement for Mandrill for the last 2 years, I can fully recommend it. I use it for transactional email and I can send 6000 per month on the free tier. More than enough for my use case. I like the templates and templating language. Setting up sender domains and authenticating them is a doddle. Using the API is also painless with the excellent API documentation.

The only thing I dislike is that there are almost too many options. This isn't a bad thing per se, but I have probably only used about 25% of the available tools/reporting etc. I also have no need for the campaign tools and would prefer it if Mailjet only concentrated on transactional emails.

We've implemented Mailjet on our clients that needs more customization in marketing emails.

Mailjet offers more free emails than its closes competitor Mailgun. Mailgun has its own perks but if you want more emails per month go for Mailjet. 200 per day vs 1000+ a month for Mailgun. Mailjet wins when it comes to marketing emails.

Can't easily add/remove members in a mailing list. No DKIM off the bat.

Learning to control my frustrations easier :)

- cheap, compared to other email marketing tools - customer support was not that bad

I would have a lot to write here. Here's a few: - server breaks down often and the entire platform is unreachable (therefore, you can not send your newsletters in due time) - poor templates, compared to other email marketing tools (no html editing available, only import) - a looot of small, frustrating errors (faulty reports, empty reports exactly when you need them, the test email not being sent, changes in templates not saved and you have no clue why) - no auto-clean option for the contact lists - quite poor segmentation options for the contact lists

MailJet is extremely easy to use and makes the process of generating mailings extremely simple. The UI for generating mailings is intuitive and simple, yet powerful and able to accomodate pretty much anything you'd want to put into an email. I use it generally for doing newsletters to a large group of about 5,000 subscribers. The overall interface for managing Contacts lists and Campaigns is well done and understandable. Adding and removing subscribers from Contact lists is fairly straightforward and mostly great. On the rare occasions when I've needed support, they've always been extremely fast and knowledge-able, and solved the issue in short order.

Three things about Contact lists are a bit annoying: 1) There doesn't seem to be any way to automatically remove Unsubscribed Contacts: you have to download them manually, then upload them to remove them. 2) Same thing with Bounced or other Contacts that you discover from the post-Campaign analysis: there's no button to say "Remove these from my Contact List": you must download them, then remove them through the removal interface 3) Errors from uploading new Contacts is a little clunky when there are errors: again it generates a file that you have to download and look at separately. For most errors (duplicate address, typos, invalid format, etc) in the little uploads that I do as part of expanding the list, I'd just like to see the darned things immediately on the screen so that I could either ignore them (i.e. dups) or fix them (typos & invalid format). Only if the errors go beyond some threshold (say more than 10, and it could be user-settable), should it do the file-generate-and-download thing.

Mailjet helps us delivering hundreds of transtactional and confirmation emails connected to our web projects. It never fails. One of the most reliable providers I have ever met in my career.

Mailjet offer various plans based on the size of your projects (there is even a fully functional free one for very small projects). It is very easy to set up, it gives you a lot of different choices to setup domain authentication (preventing your emails to become spam). No frills, everything in its right place and always working. The interface is very clear in order to communicate to developers which data they should use to integrate their software with mailjet email service, and what to do to avoid black listing, spam, etcetera

Sometimes their service for automatic detection of domain owners is blocked by firewalls. Thus you need to be able to edit your domain's DNS setting to authenticate the sender.
