"Run don't walk. Choose a different provider"
What do you like best about Twilio SendGrid Email API?

It is free and the setup was easy. Purchased through the Azure marketplace.

What do you dislike about Twilio SendGrid Email API?

The service doesn't work. Customer service is completely non existent. We used this service for transactional emails. Sending of account confirmations and receipts from our website. With a reputation of 99%, our emails were continuously getting blocked with sending IP being blacklisted by Spamhaus and others. The shared IP pool we were in must have had numerous spam accounts. We were unable to get out of the shared pool. This has happened numerous times. After 4 days and a dozen tickets, I still can't get in touch with someone to purchase a dedicated IP to remedy the problem. Moving to another provider.

What problems is Twilio SendGrid Email API solving and how is that benefiting you?

Transactional email provider for website.

"Good monitoring but expensive and no IP reputation protection."
What do you like best about Twilio SendGrid Email API?

Good reporting export and activity data.

What do you dislike about Twilio SendGrid Email API?

Reputation protection is non existent .

What problems is Twilio SendGrid Email API solving and how is that benefiting you?

Wanted reliable transactional emails to reach our customers inboxes while making sure our email sending was monitored effectively to protect our IP and Domain reputation. Sendgrid is providing a similar set of features from other transactional email providers at a premium cost compared to other providers. We get good access to download historical data to use in our own app, and they have a clean, limited functional dashboard. Where they failed is when we did get exploited when someone hijacked our email script. The exploiter was able to send off more than 400K in emails through our mailscript before any protections kicked in by Sendmail. Our account typically delivers 1000 transactional emails a day, so for any type of reputation protection kick in until 4000 X our daily average went out within 3 hours means they really don't provide any reputation protection. Once they did finally stop queuing the emails, they were unable to remove the emails that had made it through (but not sent yet) to their deferral queue. So we were stuck for the next 72 hours while their servers tried to send spam emails under our account (350k of them) domain. Even though we knew they were bad emails and were already identified. So our IP reputation went from a perfect 100% to 20% over 4 days. Now most of our emails go to junk and we have to start with a brand new IP and rebuild our reputation over the next 6 months. Sendgrid told us it was our responsibility to monitor traffic and that they had notification tools (which we had implemented but didn't notify us of the unusual traffic until it was too late - very limited notification like "you've reached 50% of your monthly quota". Pretty useless when this notification gets sent at 2am on a Sunday). In short, they do not have the capabilities nor consider it their responsibility to protect your IP or Domain reputation. 1. They do not stop a send attack until your reputation has been damaged beyond rehabilitation (pausing sending emails at 10X our daily average to wait for our approval would have stopped this issue immediately). 2. They have no way to stop emails in their deferral queue even though they have been identified as fraudulent (we watched at these known emails took our rep down from 55% to 20% even though we knew they needed to be deleted). 3. They do not see this as their responsibility. Almost all other transactional mail service providers have the ability to add in hard caps to daily email limits and much quicker technical triggers to catch unusual sending activity (most would have caught it before 10000 emails were sent from our IP, instead of waiting until 400000 were queued and sent).

"Inappropriate bahavior"
What do you like best about Twilio SendGrid Email API?

there is nothing to like about this company

What do you dislike about Twilio SendGrid Email API?

Their arrogant behavior, they are entrenched behind an email wall and their responses are obscure and irrelevant.

What problems is Twilio SendGrid Email API solving and how is that benefiting you?

I cancelled my account, because an arrogant tech all of a sudden accused me of inappropriate behavior and banned me from suing support.

"Sendgrid still has a LONG way to go, I do NOT recommend!"
What do you like best about Twilio SendGrid Email API?

Great branding, nice, clean looking website... and that's about it.

What do you dislike about Twilio SendGrid Email API?

User interphase is horrible, support is a nightmare, segmentation is confusing but the worst is the Email Builder. Utter crap. Sorry, guys. I think there's a lot to be improved before I continue to spend $50/mo on this.

What problems is Twilio SendGrid Email API solving and how is that benefiting you?

In the last 10 years I have used Mailchimp, Mailjet, SendInBlue, SendPulse and several other, and Sendgrid is by far the worst.

"Ended up cancelling our Sendgird account and using Mailchimp instead"
What do you like best about Twilio SendGrid Email API?

Not a lot - it failed to meet our purpose, switching some our Mailchimp templates to Sendgrid was a long process, uploading email lists and establishing email deliverability was tough.

What do you dislike about Twilio SendGrid Email API?

Our key goal with Sendgird was to send a triggered email series, and in setting up an account with Sendgird and realizing that it was not possible (only possible through Klaviyo) was disappointing!

What problems is Twilio SendGrid Email API solving and how is that benefiting you?

We were trying to send a triggered email Welcome Series and was unable to do so.

"If you like limited reporting and a clunky interface, then this is your JAM"
What do you like best about Twilio SendGrid Email API?

Their logo looks okay, I guess. Their OC headquarters is down the street from one of my favorite restaurants (Haven Gastropub - check it out if you're in the area. Get the burger).

What do you dislike about Twilio SendGrid Email API?

Literally everything. Their reporting is useless. Their dashboard doesn't sort emails by date of send, it just arbitrarily organizes emails. And, when you try to gain insight into how your emails performed, you can't compare emails. You have to manually export emails into an excel file and - get this - YOU HAVE TO SORT THROUGH THE COLUMNS YOURSELF. You can't select what columns you want to export. AND, when you export a selection of emails, for some unknown (*cough*stupid*cough*) reason they include the daily stats of each email for up to a week. Why? Maybe they think that data matters? Beyond that, I can't compare campaigns against each other in any sort of helpful way. With Campaign Monitor, I can compare campaigns with a couple clicks. With Hubspot, I can compare with a few clicks. Even Bronto - a company so old and clunky even other dinosaurs don't want to deal with it - can provide me relevant reporting. SendGrid? Nope. And don't get me started on customer support. I need to sacrifice a goat, give up my first born, and do a 30-day juice cleanse just to get an email from support. Only after I threatened to leave FOUR TIMES, did they grace me with a voicemail (no call - just a message) notifying me that they'd be able to get back to me about my urgent matter THE NEXT AFTERNOON. To say I'm displeased with SendGrid would be an understatement. SendGrid is more disappointing than my career choice is to my grandparents. SendGrid is more annoying than I was when I used to incessantly blast Yellowcard from my beat up Chevy S-10. SendGrid is a bigger pain in my derriere than the actual recurring pain in my derriere resulting from a bad skiing accident I had in Big Bear. In conclusion, SendGrid is an even bigger waste of time than the 27 seconds it took you to read this review.

What problems is Twilio SendGrid Email API solving and how is that benefiting you?

"Appalling Service!"
What do you like best about Twilio SendGrid Email API?

Nothing. Their product is the same as a million others out there, except it comes with appalling customer service.

What do you dislike about Twilio SendGrid Email API?

Policies and service. Subscription payment failed as I am awaiting a replacement credit card. Rather than allow several working days grace to cover such eventualities, my account was deactivated over a weekend. I was then unable to add a replacement card, as my account was deactivated. The process of reactivation is proving to be slow and hasslesome. The measure of a business is not in how it deals with its day to day activities, it is how it deals with problems. On that basis, Sendgrid come up very poorly!

What problems is Twilio SendGrid Email API solving and how is that benefiting you?

Transactional email.

"Do any humans work at this company?? short-sided way of treating customers"
What do you like best about Twilio SendGrid Email API?

nothing... I ran a campaign... and it shut down AS I was sending... no explanation... no report... I used their own blog post which shows links to check the status of your website and mine passed with no issues... so still confused why this happened... and what the decision was based on.

What do you dislike about Twilio SendGrid Email API?

Obnoxious company culture... no humanity No transparency with their decisions... rude, cold way of interrupting service... no one has replied to my complaint, despite trying to reach them a few times and this kind of behaviour will not have it impact their business?

What problems is Twilio SendGrid Email API solving and how is that benefiting you?

just sending some emails in bulk no big deal... do they think they are rock stars that they can treat customers this way?

"Not on par with the competition"
What do you like best about Twilio SendGrid Email API?

Nothing that I liked particularly, we started using the Sendgrid Marketing tools because we are Sendgrid API users, so it made sense to have everything in the same platform.

What do you dislike about Twilio SendGrid Email API?

The pricing model is not good if you have large subscriber lists that you contact frequently, as they charge $10/10k contacts. Any decently sized ecommerce platform will struggle to justify the cost of idle subscribers in Sendgrid. Also the tool is not very sophisticated in terms of A/B testing, timezone split of sends etc - overall a pretty immature product for the price.

What problems is Twilio SendGrid Email API solving and how is that benefiting you?

We use this tool for all marketing emails.

"Non-responsive, does not answer the question, no explanation whatsoever"
What do you like best about Twilio SendGrid Email API?

The UI looks great and the way the service/API is set up seems very easy to use.

What do you dislike about Twilio SendGrid Email API?

Horrible, horrible customer service. Sent an email out to support in response to an "Account provisioning failed" email (which, despite what they claim on their support page, has absolutely zero explanation of why it failed and what to do next) to ask about how to proceed with the account verification/provisioning. Days passed and no response. I next opened a ticket directly in their customer support portal asking, specifically, what are the next steps for verification and why was my account not provisioned? Their response? "Hi there, Thanks for your reply. The SaaS that we use for vetting new accounts does not provide us with much granular information in terms of why an account was failed. All I can tell you is that it has something to do with the dedicated shared IP address, but unfortunately I can't see any more detail then that.   Best of luck to you in your future endeavors, and I apologize for the inconvenience. Kindly, Erika" So what the hell does that mean? Sure, fine, you don't know why, but you didn't answer my main question: what are the next steps I can take from here? At the end, I had to ask again, before they finally told me that in actuality, "Your account cannot be provisioned at this time" actually translates to "Your account will never and can never be opened/provisioned. Look elsewhere." If we can't use the service that's fine, but why is getting a straight answer from them so hard? Their customer support seems very shifty and evasive. It's probably for the best that we won't be using them.

What problems is Twilio SendGrid Email API solving and how is that benefiting you?

We were going to use them for transactional email (e.g. order confirmation, order receipts, shipping notifications, etc). No benefits though. We'll be using Amazon SES instead.

"Sendgrid email is the worst"
What do you like best about Twilio SendGrid Email API?

They were the worst company to deal with...they over charged and never delivered for three of our clients. They promised a credit never gave it then charged over $2100 for doing nothing.

What do you dislike about Twilio SendGrid Email API?

We disliked everything and warn others to stay away. We provided them with opt in lists they only sent out 25% and charged us for 100% and over charged us by mistake , then promised a credit and claim our customer list wasn't good. We moved the same list to constant contact and no problems. Sendgrid email lies, cheats and fails on all levels.

What problems is Twilio SendGrid Email API solving and how is that benefiting you?

We were sending an opt in lists for our client to provide client info and credits to accounts. We were attempting to communicate with clients.

"Terrible user interface, numerous problems with API"
What do you like best about Twilio SendGrid Email API?

The dashboards SendGrid provides are relatively helpful and clear. Their customer support is also decent, though you'll have a very tough time finding the phone number for it.

What do you dislike about Twilio SendGrid Email API?

SendGrid has put no effort into making their interface easy to use. If you forget to fill a field out, you can click a button a thousand times and get no feedback on what you did wrong. Certain sections might be off-limits to you—rather than telling you why or simply greying them out, they will redirect you back to the dashboard page. Their SMTPAPI simply didn't work for us, and there's was no feedback anywhere about why it went wrong, though the API call itself seemed to succeed. Their support telephone number and email is nowhere to be found on their site. As a developer and a marketer, I would never use SendGrid again. All-in-all, it's an extremely poor service with very little effort put into making it seamless for users. They are clearly riding on their long-standing place in the market and are doing nothing new or helpful for users. Go with a newer, friendlier service out there—you'll quickly realize which ones care about their users.

What problems is Twilio SendGrid Email API solving and how is that benefiting you?

Transactional emails, triggered from our backend.

"Multiple problems with SendGrid, too many good competitors"
What do you like best about Twilio SendGrid Email API?

The interface is OK. The documentation was barely OK.

What do you dislike about Twilio SendGrid Email API?

Numerous problems. Import of 18K worth of customers didn't work. I am an experienced engineer and know that my CSV file was correct. Another problem was changing a login setting for a 2nd user and it caused the option to change their login credientials to vanish and required them to fix (and it took them two days to get back to me). Finally, when I tried to cancel the account it simply shows you the same page you try to cancel from with the Cancel button disabled. Can't believe these clowns have a decent rep.

"SendGrid Email marketing Review"
What do you like best about Twilio SendGrid Email API?

I liked Yoobly, a CRM for my niche of marketing Yoobly aligned themselves with SendGrid for the email marketing integration. At first, it seemed to be easy to use. Sendgrid was giving you a total overview how email marketing worked,= though I had no time to learn all the details of email marketing. All I was looking for was that my emails were send and sad to say they were not. Of all things that was my Christmas mailing and the most important of the year.

What do you dislike about Twilio SendGrid Email API?

My most important mailing of the year was not sent to my customers, because of something not set up right. I was ASSUMING my emails were send all along. Nobody contacted me that there was a problem, or made me aware there was an issue of sorts. I surely never did find out what the problem was because my CRM showed me all was well with my email campaign. I was NOT a happy camper and quit using the whole kit and caboodle.

What problems is Twilio SendGrid Email API solving and how is that benefiting you?

I wanted Sendgrid to be my email host because my CRM company Yoobly chose THEM to be my email host. I previously was with mad Mimi and was used to top notch customer service. send Grid answered me 2 days after I had an issue and actually: My issue, why my Christmas mailing never went out was not ever resolved.

"Easy to run into deadly traps"
What do you like best about Twilio SendGrid Email API?

The price was good and the tool was ok if not super user friendly.

What do you dislike about Twilio SendGrid Email API?

The fact that they don't take reasonable precautions to protect you against making mistakes Their incredibly difficult and condescending customer service when you do Old fashioned UI

What problems is Twilio SendGrid Email API solving and how is that benefiting you?

The most important result of using SendGrid was: lost time and frustration (whereas using MailChimp resulted in satisfaction)
