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.

Mailjet is a good value for money if you're on a budget. It's relatively cheaper than other providers. It offers basic features for an email marketing service. But if you'd like features like automation, testing, templates and usable statistics, you'll the need the premium package which is triple the price.

The free tier Mailjet offers comes with 200 emails/day, 6000 emails/month. When you upgrade to the essential package, you get up to 50k emails and features like segmentation and email verification for $35/month (10% discount annually.) It's a good value for money if that's what you're looking for.

Free tier doesn't give you enough features to try to determine if this is the right email marketing service for you. You'll eventually have to get at least the essential package to get a full view of what they have to offer.

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
