Muy buena a comparación de Mailchimp, es muy fácil de usar.

Buena plataforma de Email Marketing

Good Email Marketing platform

Sendpulse offers many features that would meet most of your business needs, and once you get started with the software, it's hard or unecessary to look elsewhere. It offers features like Automation360 which, as the name suggests, automates many actions on your behalf. The API integration feature is a nice one to have, as I don't want to manually import my thousands of emails from old services.

One-stop shop for all your digital marketing needs

We started using SendPulse for our software company StaffCop to deliver webpush notifications to get better onboarding. Got incredible 45% CTR and 10% increase in the entire onboarding process. Two months later we decided to switch from MailChimp to SendPulse to create more intelligent email+webpush transactional platform

Webpush + Email. Here's why we use SendPulse

So – I am going to caveat this whole thing with – if you’re not interested in using the API or you are not coming from another service with an existing API integration, this probably won’t apply to you.

Summary: 2 different API’s, both awfully designed, both poorly documented, both with completely different authentication methods, credentials etc. however, the application itself is great, so if you’re not using the API, it’s probably fine.

Full Review:

SendPulse has a functional API, but it feels like it was created by someone that read a REST API book of best practices without really thinking about how people would / should use it.

My biggest problem is the way authentication works (on the main API which is for sending your campaigns, managing subscriptions etc.), sure it follows all OAUTH standards, but this means you need to manage identify on your application so you send all the correct tokens etc., it feels very Salesforce, not Slack (if you have used either of these API’s you will know, Slack is easy, Salesforce is really really hard) – another comparison would be that it feels like IBM made this software when you are using the API, not a start-up.

If you are coming from something like MailChimp – the MailChimp API is easy, send a request with your API key and whatever you are requesting happens or you get a meaningful response, I have seen many garbage responses from the SendPulse API – you cannot guarantee JSON will come back, sometimes you get HTML, sometimes you get a weird HTML 404 page with some Yahoo copyright notices all over it, it all depends on how mangled your request is – so on top of having to worry about handling identity, you need to handle all sorts of strange responses not just JSON – and therein lies the next problem – DOCUMENTATION:

The API documentation is god-damn-awful, and because the API is quite complex and / or obscure in terms of how you request stuff, you often end up with garbage responses and have to trial-and-error how stuff works.

SendPulse has created a bunch of libraries to make this easier, and if you want to hang your PHP application by using their library, then go ahead – but if you have some kind of background task manager you will probably have to write your own stuff, which in most cases would not be too hard, but because the documentation is sparse, I really struggled to do even the basic stuff with CURL on the command line – if I was to suggest anything, provide CURL examples like Slack does, at least that way I could reverse engineer the CURL to sort out the lack of actual documentation (again, it’s a problem because the API responds with junk HTML if you get your request wrong so you don’t know what is actually wrong and have to trial-and-error a lot).

On top of all of this, if you are planning on using the SMTP send-alone API, you have a completely different authentication process – one that I still have no idea how to make work – this is what the documentation says about how to authenticate: http://i.imgur.com/sVAc3II.png

(the original documentation is here, but I think you need to be logged in to view it: https://login.sendpulse.com/manual/smtp-api/)

I personally have no idea how to authenticate against this SMTP API. I have not yet asked support about it because they are looking at something else for me that is more important, but I just don’t…….. what….. from the documentation (a required parameter to authenticate, IV): “iv – an initialization vector, encrypted by a public key with an OpenSSL Library usage” – what is this? Why is it never mentioned again? how do I get it? 

And most importantly, why on earth is it different to the (already convoluted) other OAUTH authentication on the main mail API? 

Anyway, to wrap this up, I picked up SendPulse because I needed both templated / campaign based email and SMTP / transactional email and I previously had MailChimp, but did not want to pay for Mandrill because my SMTP volumes were super low.

SendPulse is fine, but I have wasted more time than the money I would have saved just using Mandril, however if you can get over all of this, the product is actually pretty good which is why I have not left a steamer of a review score, and as I said at the start, if you are not using the API it is great.

I just hope they release a new version of the API that focuses on functionality rather than horrible REST standards (although I’m not convinced all of this is standards compliant), which I think have generally been thrown away by the new-wave tech start-ups so people can quickly deliver value.

Good but API is hard work

President

I've had a very positive experience. The help desk was able to respond to some of my questions pretty quickly, I like the functionality and my emails look good.

TA Scheduler

I have had instances where the emails sometimes end up in the spam folder or promotions folder, which can be annoying and needs to be figured out.

Automotive Salesman

Mailchimp is very great software. I like how it's easy to interface, and how you can clean the data.

Youth Pastor

I like how Mailchimp keeps track of my audience and helps me categorize them for different types of emails. I also like being able to create appealing and interactive emails for my viewers.

Pastor

The greatest benefit to using this program is the integration possibilities. It is compatible with a lot of the other software/programs we use so integration was seamless and saved time & money.

Owner

Mailchimp is used by many which means that spam filters are more likely to tag your emails as spam. I did not have any other problems with Mailchimp.

Freelance Web Developer

Their dedication to improvement is a positive sign for the company. There is a reason that they are the industry standard.

Mailchimp is the best, I have learned about their features, and they are perfect especially for a beginning business or business with a small following. They make it really easy for you to use.

It was great - I love them and suggest them to all friends getting started, I wouldn't trust any other company for a product in this price range and offering.

Professor

The templates are great and quite efficient. It's really easy to set up a campaign and the option to make a landing page right there is awesome.

Editor 

This software is great for social media, has advanced features with it and allows you to have a free trial with it. The email campaign is very straight forward and easy to use.

Marketing

For a company that's been around as long as Mailchimp has, it's crazy to me how bad the UX/UI is. It's just hard to use so much of the time.

Data Analyst 

Very confusing,  very difficult to figure out where to click , also when you input a wrong email address it blocks your whole process of sending emails to others.

Mailchimp a great email marketing tool

I like the ease of use of this software and how you send 2000 emails for free before you transfer to a paid membership. They are a great company and have been in business for years.

Business manager

I love to use mailchimp for email marketing most especiallly when i want to generate lead. THEIR Landing page is superb.

Senior Software Engineer

Its broad feature set and ease of use are an amazing help to a new company just getting started. If you're not looking for custom integration or transactional emails, this product is one of the best.

head of operations

It has been a good experience, would recommend specially if you are just starting creating your newsletters and want to practice before spending a significant amount of money on this type of software.

Customer service 

The easy to read interface and the ease of printing. The hospitality from customer service is great.

She said they would not respond to the scammer, even though they have their email. I fault the company for having no protocol for fraud.

Independent Researcher

The overall experience with SendPulse was very nice. It is responsible for delivering grand communication and yielding excellent results.
