You have to build your own interface to use the Twilio API. Or pay for a software that can use the API, which is easier and cheaper. The Twilio interface only allows you to monitor usage, create reports, billing management, and program IVR. It doesn't provide an interface for your sales team to use.

I like how complete it is and all the API possibilities. You can achieve so much if you know what you're doing. You can create a call center and monitor everything, including recordings. SMS marketing, ringless voicemail, etc..

As you scale, it gets very expensive (no discounts at all for loyalty). Zapier is losing its market share to Make, Pipedream, and Pabbly. Soon the same will happen to Twilio.

Twilio handles all the inbound calls for my website. I ported a vanity 800 number from a another provider to Twilio and after a quite lengthy setup process that involved lots of customer service calls it was up and running. After that you can pretty much leave it or do some minor changes relatively easy. Now when customers call they can choose from an option tree to troubleshoot their issue or they can choose to talk to an agent (me) and if it's during business hours the call gets forwarded to my cell, if outside of business hours they get my voicemail. Works great! I also have it embedded in my website for a chat option that more people actually use.

Twilio has every option under the sun, there's nothing call center related that they can't do for you. You could set up automated systems to perform mundane tasks for you, record and inscribe all your calls and even have a call center set up to help troubleshoot issues and direct calls. You can get add-ons from GitHub, integrate into your website especially Shopify and answer calls with a number that you can bring with you or they provide straight to your cell phone. We're talking local numbers and 800 numbers even though you may have to pay extra.

Very steep learning curve. There are so many options and so many ways to use this service including third party apps that you could get confused quite easily. Also their 2FA process is tedious which if you're not careful could result in you losing your number.

This marketing and communications software has been easy to use and reliable. Twilio is so accurate.

Twilio is flawless. It makes SMS marketing efficient.

We have been a SendGrid customer for about 7 months. We use the service to handle the transactional emails from our website. We have been satisfied with that service and decided to also use them for our marketing campaigns On September 30th we exported our MailChimp contacts and cleaned up the data. On October we upgraded our SendGrid plan to Basic 50k, contacted SendGrid support, informed them what we were doing and asked about the use of Tags. We then imported 47k contacts, prepared a time sensitive single send marketing piece which we released on October 2nd to our complete contact list. SendGrid shut down the campaign, disabled the links in the 13k emails that had been sent, making them useless, and suspended our account. We have been unable to reach SendGrid to resolve this. This action, and lack of it by Twillo/SendGrid has significantly impacted our business as the campaign was in support of a live continuing education course scheduled for Tuesday 10/3. At this point we are trying to salvage what we can by moving to another marketing service.

We were migrating our email marketing from MailChimp to Twillo's SendGrid. Relative to MailChimp we found SendGrid's email design tool to be more flexible and easier to use

Customer support: Two issues1 -Customer support is difficult to access. The support phone number listed on Google is disconnected, there is no chat, "Contact support" on the website requires the user to fill in a text box labeled "Tell us your issue." We've tried this multiple times only to get an error message: "There was an error retrieving results for your query. Please try again." We've managed to get multiple messages to SendGrid Support by responding to previous support ticket emails. I see some one at SendGrid has deleted all but one of these. Obviously someone knows we have an urgent issue but no response and it has been over 18 hours since our first request for support. 2. When we informed Customer support that we were migrating our marketing champagne from Mail Chimp to SendGrid they failed to inform us about the possibility of the automated account suspension we have encountered, and how to avoid it .
