My overall experience with SendGrid has been positive. I appreciate its reliability, detailed analytics, and user-friendly interface. My only concerns are with pricing scalability and occasional customer support challenges, but the platform consistently delivers effective and impactful email campaigns.

SendGrids high deliverability rates, solid tracking metrics and easy to use interface make it a very attractive offering in a competitive space.

The pricing structure mean that scalability can be a concern, there are some sudden jumps in pricing. The step from 200k to 250k emails a month takes you from $89.95/mo to $249/mo which is a suddenly 3x cost increase, with similar 2x increases at the next intervals. Having unit-based pricing would be less stressful than suddenly crossing a threshold.

In addition to having their emails filtered as spam, sales representatives were unable to monitor their recipients' actions when sending them via their email client. Our problem was fixed via Sendgrid's email API.

Integrating with the email API is a breeze. When compared to other mass email service providers, we have seen that SendGrid consistently produces the highest interaction rates. The ability to automatically retry sent emails is a good bonus.

There is no consistency in the percentages of emails opened or clicked. There is currently no mechanism to block measurements that originate from email service provider bots.

We needed a way to improve on the fairly dismal email deliverability in client WordPress sites, and our primary web host had an integration with SendGrid. After seeing great improvement in deliverability with SendGrid, we have started using it on many sites hosted elsewhere.

The biggest pro is that SendGrid has a free tier -- increasingly their competitors are moving away from having one. As a result, we can use SendGrid with many sites to improve email deliverability within Wordpress for free, and it's still affordable if it's needed more.

Email validation is not available until you reach the Pro level, which can be a bit pricier for smaller sites.

What a horrible experience. After signing up as a new business customer as part of a new marketing strategy my business implemented, SendGrid immediately suspended my account for no reason (after taking my personal information), and an agent then proceeded to tell me some magical 'vetting' system determined I wasn't eligible to use their service.After asking how an earth they could 'vet' me considering they haven't even obtained anything about my business they proceeded to tell me they can't tell me why and that their decision was final.Appalling service, I genuinely have no idea how these people even have customers to begin with if one can't even sign up....

Absolutely nothing, couldn't even sign up...

Everything, because they discriminate on who signs up to them, and give no explanation for suspending your account after taking your personal information.

As long as you don't have an issue and need CS their tech works great and have a good value proposition. When I can find another company with a similar value proposition and even decent customer service I will switch.

They present a good value and a dependable product

Customer service is terrible. It used to be pretty good. They have made getting service more difficult, and when you use the chat they try to redirect you away. So when you chat you get in a queue and they text you when you are next. I get a text go to the chat and it says >1 Minute. I stay on for 3-5 minutes no one is there, I go back to what I am doing and when I go back the chat closed. Do it all over again, and this time within a minute someone gets on. I message 7 times my question and issue, 10 minutes go by before I get an answer. The whole process is terrible and purposefully by design treats their paying customer like trash. You don't matter, your time doesn't matter, and in fact you are an idiot for not figuring out the issue on your own. Even when my question/issue was something ONLY they can do. I do not have the ability to increase subusers, only they do. I wish I could say that this is a SendGrid issue, almost every business has rearranged their CS to serve employees, which usually is at the expense of those who pay to make the whole operation work.

Overall SendGrid offers a great service with competitive pricing and great performance. Unfortunately the deliverability for emails hosted on Microsoft servers is not that good and other providers might be needed in those cases.

SendGrid is a well priced ESP with great delivery performance, near instant webhooks and highly configurable. Their API is quite straightforward to use, minimizing integration costs.

When using a shared IP, deliverability to Microsoft hosted email addresses is really bad, most emails sent to Outlook or Microsoft 365 organizations end classified as SPAM and the only workaround withing SendGrid is to have a higher cost plan with dedicated IP addresses, having to build the IP reputation from scratch. Also support takes days to reply to most concerns.

My email deliverability and response rates have drastically improved due to customers receiving my transactional emails.

Integration is dead easy and the free tiers are fantastic for small businesses and to try out the software.The Marketing Campain feature is great.Documentation is comprehensive as well. The real time analytics and reporting is fantastic.

Payment issues and customer service response times are a bit of an issue.

Has high potential, very secure with 2FA, limit the amount of templates you can have in each account and overall ok

Easy to use API, advanced features, relatively friendly and very secure with 2FA foreced on you and every user in the system

Customer support can improve significantly (didn’t reply to my ticket for more than 2 months, I had to approach the sales department for making sure my ticket is reviewed)

I just needed to send emails for email verification and such, I was building a prototype and all good and easy. Things happened and the prototype was put on hold for almost a year. Recently I restarted work on the prototype and for some reason invites weren't working, I haven't changed anything nor touched the configuration. After accessing the SendGrid website I found out my account was closed due to inactivity (fair enough I guess) and I would need to create a new account, upon creating a new account I'm faced to a screen that says my account was flagged by "the system" and I need to answer a few questions, one of them is the random username that I chose and don't remember... I tried to contact the support to find that their support page requires you to be login and funny enough you need an open account to do anything... Basically the support website was useless to my newly found closed account, so I did the other thing they recommend on their support page, reaching out to twitter support @SendGridSupport , which I did, on their response there's this text: "If you do want to take a look at further options for the deactivated account you can reach out to our HelpDesk by emailing help@sendgrid.com(...)" - Cool I can get back my old account if I send an email... I sent the email, explaining that I got locked out, the customer rep sent me a pasted response. At the end I cannot get my account reactivated and need to send proof of my domain ownership(which I updated CNAME)

Quite easy to setup, integration with firebase was easy enough

User experience, account closed due to inactivity and without any email or notification. Customer support didn't even read what I wrote and just copy&pasted a response. New account flagged by "the system" and misleading information provided by their twitter support.

I really enjoy having Sendgrid in my toolbox of things to enhance my business

Send has been an asset in my business to help me get better email deliverability in my marketing campaigns

For me, it took a few minutes to get it going in the way I use it, but wasnt too difficult

Best tool to send emails and also keep track of them

So far no cons. Its very easy to use and maintain.

All in all, a really easy tool for weekly or monthly email marketing. Thanks to the lists, messages can be targeted to different user groups.

A straightforward and convenient tool for email marketing. In the preview phase, you can see how the email looks on different devices. That is very useful.

The platform's email editing tools are too simple. If you want finer and more elegant features, you should code them, depending on which feature you want.

After connecting SendGrid to my WordPress installation the notification emails for my web forms send without any issue.

Getting the "From" domain verified can be challenging sometimes. The process isn't as simple as it could be.

It still meets our needs at a great price!

It is a great all in one tool for sending emails in bulk

The dedicated IP address is only available on the Silver or higher tied

Sendgrid handles all my mailing campaigns and I have stuck with it from day one to date. I like the email deliverability and tracking metrics offered by SendGrid and will stick with it for the foreseeable future as everything works smoothly.

It was very easy to integrate with my existing stack. SendGrid has really worked hard to make sure it's easy to use their software with other services out there. Most website builders by default ask you to integrate Sendgrid as your emailing service, and that was the case with my website builder. It was really easy for me to get started as all I had to do was add an API key in a provided input field. SendGrid did all the heavy lifting and I did not have to do any coding or even go through the API documentation(which by the way is very comprehensive ). You fill that that is the case in so many services that integrate with SendGrid, integration is light-work.

It is a little expensive, especially when sending a tonne of emails out and having a lot of contacts. Your email totals low-key add up when you have multiple drip campaigns and transactional emails set up. If you have a small budget it's really difficult to get measurable success on SendGrid as I found out when I just started while having a very low budget. The best way to get the best out of SendGrid is with a substantial budget, and that's a bummer when starting out.

The tool is good. But their initial configuration is so terrible I recently moved to SendInBlue. This tool used to be so good but trying to make it secure they just ruin it for devs. The customer supports is not really responsive. In past years they have grown so quickly they could not keep up their old qualities.

It has a really good transactional API and the dynamic template is nice and easy to use. Ruby gem for SendGrid is good as well.

The configuration part is terrible. When you add Sendgrid add-on through Heroku it gets blacklisted instantly. When you tried to a new account the signup process is terrible. They have added 2FA and sender authentication that is a good thing but that is a nightmare for a project with multiple devs and having multiple environments. They need to add features for developers.

Sendgrid lives up to its reputation as a market leader for email. Be it marketing, authentication and transactional emails. It provides a plethora of options and functionality that meet most business needs.

The fact I use sendgrid for transactional emails says a lot. The api intergration is a breeze, as are all of its parameters available. The email monitor tools as well as the disposable email detection have proven particularly useful. Third party intergration is easy with the likes of Firebase, FaunaDB and node cloud functions.

There isn't any particular thing I have a disliking for in all honesty.

SendGrid is the best option that assembles a host of benefits in one place; its editor, analytics and reports, and particularly, its powerful feature to prioritize campaigns and increase performance let every business excels.

SendGrid is the best option to boost your business ahead or rather your marketing emails; its detailed reports on clicks, opens, subscribers and even spam lets you revise or edit your campaigns and thus increase conversion. SendGrid is best known for its editor, which lets tailor your emails according your needs, both demographic or geographic.

Actually, I become slow to recommend SendGrid due to its limited features of contact management; it does not provide many options compared to Mailchimp. I also did not like its pricing, which determines the quality of your SendGrid dashboard.

Our use case is simple: We need reliable deliverability of emails to up to 2,500 addresses, three times weekly, and we need to be able to track bounces, address changes, etc. easily. Sendgrid provides that service well and at an affordable price point. It also offers traditional "email marketing" services, which we do not use and cannot evaluate. For our needs, it's a solid offering.

The media center I run submits three political op-eds per week to about 1,300 newspapers in the US (and sometimes another 1,200 internationally). Sendgrid delivers those emails in a timely manner and keeps track of bounces, etc.

Setting up to use the API from a custom email address is a bit cumbersome.

They have been amazing, support is fast and helpfull. I don't remember having any downtime with them ever since I joined the service.

Sendgrid has an awesome service for email marketing and transactional emails. It works 100% of the time, the support is amazing and it even gives you a free plan that will serve most people.

The price for email marketing (contacts) is a bit too high for me. It could be packed with way more interesting features. Also the editor sucks and it never sends the mail like it shows on the screen. But I do not use this feature.

Sendgrid is great with delivering emails and is undisputed in transactional emails . Use it for its top notch deliverability, reporting and analytics as no other application even comes close to it in these areas but as a total email marketing platform; it lacks behind as it has very few campaign automation features, it is difficult to get used to and has a poor customer support. It is also slightly more expensive than others and falls in the middle of the lineup in terms of pricing.

Deliverability, reporting and analytics and email validation are the areas where sendgrid is at the top. It even tells you if the email ids you are sending emails to are active or are misspelled or are disposable. It has excellent reporting features and lets you know the emails which bounced, got opened or got unsubscribed. Its email editor is good wherein you can edit existing templates using drag and drop features and you can also use tags for sending personalised emails.

Campaign automation, segmentation of contact lists are severe drawbacks of this application. There is hardly anything you can automate in terms of automating your campaigns or automating when to send emails on certain action points.

Excellent

We use sendgrid for our enterprise application for all purpose ranging from notification, verification and transactional information. We switched from a competitor that was burning our pockets and had a lot of issues. the pricing was a balance between our budger and our requirements and send grid just fit into the grid for us

No complaints. However the suggestion to the manufacturers would be to improvise the documentation for this product to provide more use case specific guidance to help users

It did what we needed it to do, so that was good. We used it for over a year for monthly newsletters, but as soon as our marketing budget allowed it, we switched to MailChimp.

It did work and it did send the email newsletters that we needed it to. Therefore, it wasn't a complete waste of money :D Compared to many other options for email marketing, SendGrid was one of the cheapest options (except for sending the newsletters manually through one's email) and that was one of the reasons why we went with it.

It's got a lot of features, but they feel half-baked (I'm sorry, but they do.) For example, you can unsubscribe those whose emails have bounced or who unsubscribed. But in order to do that, you need to download those lists, then upload them to a special list you can call "unsubscribes" or whatever, and then, right after you've imported this list, you delete it - along with associated accounts. THIS deletes the people who bounced from your lists. Seriously?! The annoying thing was the styling within the newsletter. I am a perfectionist, so all text sizes and everything should be consistent. However, SendGrid kept changing the styles of my text and I had to choose "Normal" several times (even after copy-pasting the text from Notepad that doesn't support formatting AT ALL). And if you click on "Edit HTML" (which I often do because it's a fast way to clean away all the annoying tags), SendGrid would convert my block to HTML and would have an entirely different set of styles for it. Also, the support pages were written for someone who is native to this SendGrid thing and not a newbie. Despite doing email marketing for years, I had a hard time understanding what I need to do.

Overall, the experience was solid. Price and customer service were great. Unfortunately, the spam and email block issue was a deal breaker.

The pricing is great. Easy to use API with lots of documentations. Their user interface is straightforward. The customer service has always been pretty quick to get back to me. It's a popular service with a lot of integrations available.

I was a happy user of Sendgrid for a long time, but emails sent with the service always went to the spam folder for Microsoft email services (Outlook, Hotmail, MSN). This could never seem to get resolved, even with a dedicated IP that they offered. Then recently, Microsoft started blocking the emails. I found out this was because a spammer had used their service and got the shared IP blacklisted. They were unable to help me resolve it swiftly, so I had to leave the service, because we have a lot of people who use Microsoft email services.
