Some hosting accounts have issues with deliverability coming from Wordpress. SendGrid solves that as an SMTP.

"Reliability in email"
What do you like best about Twilio SendGrid Email API?

My website sends a fair bit of email to customers related to services that they are getting from me--confirmations, reminders, cancellations. It is essential that they receive these emails and I have found that my messages ALWAYS get through. I never hear from customers that my email goes to the spam folder. It is delivered and I value that highly. I also really value the open tracking and click tracking that Sendgrid provides as it better enables me to see that customers are actually getting and engaging with my messages. I found out about Sendgrid through my use of Microsoft Azure and while I don't use Azure anymore, I have stuck with Sendgrid.

What do you dislike about Twilio SendGrid Email API?

Sometimes I need to be able to track emails from a while back and I have not found a way to get access to a full history of sent emails and whether they have been opened.

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

I do not use the Email API. My connnection to SendGrid is via SMTP.

"Simple and powerful"
What do you like best about Twilio SendGrid Email API?

API functionality, ease of use, powerful insights into metrics.

What do you dislike about Twilio SendGrid Email API?

That we don't use all the features available like campaigns, etc. At some point in the future, we may expand and use some of the options available to jazz up purely marketing emails.

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

A controlled source of sending rate sheets, etc as marketing emails.

"Reliable and Scalable Marketing and Transactional email capabilities"
What do you like best about Twilio SendGrid Email API?

All-in one transactional and marketing email solution that appeals to both developers and marketers. Easy to integrate API triggers into external sites / apps and also easy to integrate with 3rd party marketing stack providers. Full suite of solutions from managing marketing lists to creating campaigns or transactional triggers. Category-based transactional reporting gives me lots of flexibility in how to roll up /aggregate reporting data. Robust activity exports out to other marketing stack tools for open / click / send based segments.

What do you dislike about Twilio SendGrid Email API?

I would like to see reporting developed out even further. e.g. more robust report data export options, more ways to slice and dice and analyze reporting data from the UI.

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

Integrating a multi-layer marketing stack that leverages disparate data sources and tools to create a unified and robust customer communications and marketing platform. Great value for cost.

"Great if you are worried about deliverability. "
What do you like best about Twilio SendGrid Email API?

I've used Sendgrid for both marketing and transaction emails. It's less user friendly than other options but it's reliable and I trust their consistency with delivery. If anyone is having issues email delivery I always recommend Sendgrid for an easy solution to remove their headache. It's api means makes integration easy. It's very reasonably priced and would be great for smaller businesses with low budgets if they have a team to get it set up.

What do you dislike about Twilio SendGrid Email API?

It's not as user friendly as newsletter programs so I usually only recommend it to larger business or techy teams. The other occasion where I recommend them is if someone has repeatedly had issues with delivery because I think this is where Sendgrid shines. There is a larger setup barrier but this is generally worth it because all this setup means better reliability for your messages and campaigns.

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

Email delivery problems! It also has great email marketing features that add confidence that your campaign will be delivered but it's not very user friendly as other newsletter programs.

"A one-stop shop."

I love the ease of configuration when integrating SendGrid with our in-house or 3rd party applications. In addition to that, SendGrid has proper Feedback loops set up, which allows us to scale our operations accordingly.

What do you dislike about Twilio SendGrid Email API?

It can be difficult to really get the answers you need when you need them with send grid because their UI has so much available to it.

We use SendGrid to send emails from various 3rd party and in-house platforms that require an SMTP server in order to work. SendGrid has great Feedback loops set up and this allows us to scale our email campaigns accordingly.

We use the API to create a separation of concerns between our various environments. SendGrid makes it fast and easy for us. No more email servers. No more headaches.

"Great API for sending transactional emails"
What do you like best about Twilio SendGrid Email API?

We currently use SendGrid for our transactional emails as well as our marketing emails (they recently added the marketing piece). It is flawless for transactional emails. I really like that I can have templates and edit them directly on the SendGrid site and then pass in whatever data I want via API when sending the emails.

What do you dislike about Twilio SendGrid Email API?

The marketing email tools are still being fleshed out. I'm not complaining about them, but the email editing tools aren't anywhere near as easy to use as Mailchimp's editor. I'm optimistic for it, though.

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

We're able to jump in and send out emails to customers who are already customers, who opted in to marketing emails during a purchase. I'd have to plug that data in to a different service and have disparate data if I didn't use SendGrid for marketing as well, since we're already using them for transactional emails.

"Excellent SMTP Relay for User Interaction"
What do you like best about Twilio SendGrid Email API?

An amazingly easy to setup SMTP service to deliver notifications to a large number of users of your web application or service. The API is solid and well documented, in addition, it's a trusted SMTP, so chances of your emails getting bounced are less. It's incredibly easy to setup and use. Pricing is incredibly competitive and great for startups if you're using under 200 mails a day.

What do you dislike about Twilio SendGrid Email API?

There seriously isn't very much about this tool that I dislike, it does everything it says it's supposed to do.

"Twilio sendGrid email Api is the best service for email varification at testing time."
What do you like best about Twilio SendGrid Email API?

I'm a full stack developer. I have used Twilio sendgrid at my one of project, in that project basically I have to varify that user when he or she registered. This service helped me to send the email for varification to that particular user. Some things are the best in sendgrid which I appreciate that, like it is open-source. Even we can use in our project at a testing time. It is also provide the range of mails to send in one month. Anyone can use the email service which have provided by Twilio sendgrid email API.

What do you dislike about Twilio SendGrid Email API?

That one thing which I have faced when I have create my account at Twilio sendgrid. I have faced some error, like you are unauthorised, I am not able to varify and Authorize myself . So i wish this kind of issues should not faces by others users of Twilio sendgrid.

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

One of the problem which I had faced, to varify your account after the registered your self at Twilio sendgrid. Some time user can't able to varify their account. So I would like to say that if this problem solved at this time then after the allover services which have provided by Twilio sendgrid is much better than others. All overall the experience with it is so good.

"Keeping track of sent emails has never been easier"
What do you like best about Twilio SendGrid Email API?

Sengrid has been such a wonderful system to use to keep track of the emails being sent out by our automatic system. The ability to check if emails bounced, have been blocked, if the emails were opened and even clicked on has been severly helpful in our efforts to educate our guests/customers about the importance of confirmation emails and accountability. Nothing negative to say about how it all works hand in hand together

What do you dislike about Twilio SendGrid Email API?

One small thing that really bums us about (seniors here) would be the limited dates you can use you generate emails sent to a specific email address. Would be very nice to maybe push it to 3 months if possible however other than this, Sengrid is just wonderful !

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

Sengrid has helped our company keep track of the automated emails being sent out to the million of guests we cater across the worl. This has helped us ensure that accountability and visibility is present across all boards, both with our guests and the employees

"The must try software to upgrade your cold email campaigns"
What do you like best about Twilio SendGrid Email API?

The best part about Twilio SendGrid is it's ease of use. Uploading contacts and creating email campaigns is a seamless process and the analytics post the campaigns are detailed and helpful. SendGrid also allows for easy creation of email templates and our design team has been able to create high quality templates withembedded sign up forms on multiple occasions.

What do you dislike about Twilio SendGrid Email API?

While SendGrid is a tool that is useful on so many fronts - the pricing for the Pro Package is on the higher side. There are many newer startups coming out with cheaper tools for cold outreach and if you use SendGrid for just email campaigns- you might just switch because of the price.

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

SendGrid is really helping solve for better email deliverability - especially for cold email outreach campaigns. You can upgrade your emails and create more targeted campaigns through SendGrid

Sendgrid made it easy for use to offer our customers a simple way to send emails from out application. We offer a CRM with full email intergration thanks to SendGrid.

What do you dislike about Twilio SendGrid Email API?

The most complicated part was getting it to work with our API and getting it setup on our customer's end (our customer's arent technical so setting up the correct DNS records can be a bit complicated.) Further, i got no complaints!

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

SendGrid has helped us provide a safe and easy solution for our customers to send emails from our CRM. SendGrid made it also a lot easier to have a clear overview of our mail activity and how much gets opened or not.

"SendGrid salesforce integration"
What do you like best about Twilio SendGrid Email API?

I have used SendGrid integration with salesforce to send emails on a particular event it is straightforward to integrate into the system and it very responsive to the change of the event

What do you dislike about Twilio SendGrid Email API?

On a particular event that is to update a specific field in salesforce, it is not responding so I have to send an email on the update of the whole record. I haven't found any solution to that so there are still things to update

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

I have to send an email whenever a specific field of a record is being changed, According to me it has been very efficient with SendGrid. It is a better solution than salesforce's email alert.
