Smarty

Pros: As a wedding stationery designer, I love how accurately Smarty validates both domestic and international guest addresses. It catches missing apartment numbers, formatting issues, and even duplicate households before anything goes to print. It saves my clients time, stress, and postage by ensuring their save the dates and invitations mail correctly the first time.

Cons: Some international formats require a bit of manual double-checking on my end, especially when clients submit inconsistent data. More intuitive prompts or guided suggestions would be helpful.

Pros: Easy-to-use API that connects quickly. No problems getting accurate answers for both US and international addresses.

Cons: Salespeople are a little pushy. They keep emailing me, but really just want to be left alone. I don't need additional support.

Pros: What I like most about Smarty is how reliable and fast it is. The address validation is spot-on, and it immediately improved the accuracy of our data. The tool is simple, intuitive, and integrates easily into our workflow. It saves us time, reduces errors, and keeps everything running smoothly — exactly what we needed.

Cons: Honestly, nothing major. If anything, I’d just like to see a bit more flexibility in customizing certain fields, but the core functionality is already excellent.

Pros: It's fast in response even though we implemented it using a proxy on our app server and not hitting the APIs directly, it's still fast. Ease of implementation.

Cons: If you need county and 4 digit zip extension you have to use two end points and it's not included in the primary address autocomplete.

Pros: I love how simple it is to interact with the Smarty APIs. I wrote the integration in a couple of hours and haven't touched it in literally months.

Cons: I was going to say price but for what we get and how easily we get it I think it is a fair value in the end. When we need to expand our address capabilities we'll be back.

Pros: The accuracy is phenomenal - it's saved us from countless shipping errors and returned mail. The API is rock-solid (zero downtime in 8 months), and the autocomplete feature has sped up our checkout process considerably. Plus, international address support was a game-changer for our business.

Cons: If I'm being picky, I'd love to see a mobile app for quick lookups on the go. Also, the initial API documentation could use a few more examples for edge cases, though support filled those gaps quickly.

Pros: Smarty has been excellent to work with. Their geocoding service delivers strong match rates and fast, reliable results, which has been crucial for servicing our insurance customers in the US. The customer support is outstanding – responsive, knowledgeable, and genuinely helpful. Pricing is transparent and fair, making it easy to scale with confidence.

Cons: Honestly, very little to fault. The service works as expected, and any questions or issues we’ve raised have been resolved quickly. If anything, we’d love to see even more international coverage in future, but that’s a nice-to-have rather than a drawback.

Pros: The python integration examples were spot on! Integration into our python codes was simple. We run marketing campaigns twice a year and the monthly billing works very well for our needs.

Cons: Let's see. 1. The product works as advertised. 2. The customer service is outstanding. 3. The sales and product selection was well defined. So, looks like I least liked item number 3.

Pros: Easy integration with high availability. We switched over from another provider and it was pretty easy

Cons: Nothing to note. The documentation, customer support, dashboard, and everything else we needed was pretty straight forward.

Pros: The fact that it is fast and accurate, when met with a 4400-line spreadsheet in a new team I needed help, this was it!

Cons: Canada being in a separate search, it makes sense, but I wasted some of my searches because I didn't realize they were mixed in.

Pros: Was very easy to integrate into native mobile apps (iOS and Android). The SDKs were straightforward to use. The documentation was great. I got the iOS implementation done in 2 days!

Cons: They weren't the cheapest solution, but the others seemed more clunky. Smarty was the most developer-friendly, but in the middle of the pack pricewise.

Pros: Great customer support, and great product. We have been using it for years and haven't had any issue whatsoever. The uptime is also phenomenal, almost no failures

Cons: Lot of products and it becomes confusing to understand sometimes on what we really need. The team is helpful but they could do a better job on the site

Pros: Smarty's auto-complete and auto-correct functionalities are probably the features I like the most. But it doesn't stop there. Every address record stores the api information for that particular address, allowing me to get even more granular in accessing information related to the type of address (e.g. residential vs commercial), county, etc.

Cons: I don't really have any cons with using Smarty because it has done everything we've needed for what we use it for.

Pros: The integration of Smarty is remarkably user-friendly. The outcomes are satisfactory, enabling the development of an intuitive address validation system.

Cons: If the user is utilizing a virtual private network (VPN), the Smarty response may be 400. To mitigate this issue, it is recommended to employ a proxy, although we have not yet tested this approach.

Pros: Address auto-completion / validation is vital for our real estate marketplace to validate the address of homes online. We deal with all property types and I have not found anyone (including Google) that supports condos as well as Smarty.

Cons: Auto-complete of addresses is only for places where USPS et al. deliver mail. This is limiting for us since we deal with land parcels that are not developed and our customers cannot find the addresses.

Pros: I'd say two things: The amount of data they ahve and the tools they have to access that data. Everything you ever wanted to know about a property, they seem to have.

Cons: If it doesn't sound stupid, sometimes it's too much data to sift through easily. For the product(s) we use, sometimes not all the data is represented making handling of the data that is sent a little tricky.

Pros: Smarty APIs are really streamlined and efficient. Very easy to interface with. It's nice when a service not only provides quick responses but also backs it up with responsive and knowledgeable support. Only had to contact technical support twice in the development, very fast response time, extremely knowledgeable.

Cons: Really nothing. May be trivial, but getting to the API simulators at Smarty.com takes many clicks to get to. Would be nice to have a developer's page off the main page with all the API's for testing in one place.

Pros: Smarty's APIs are easy to use and intuitive. Our use case is related to new residential construction, and they seem to be getting newly registered addresses with minimal delay.

Cons: There are a lot of different APIs and features. Our use case is fairly specific and limited, and so it's a lot to go through to figure out the best way to solve the problem.

Pros: Excellent interface thru Google sheet extensions. Results are perfects. I like the way it directly works on the data sheet and I do not have to copy/past forward and back.

Cons: Too many clicks. 1. Extension (On Google sheet menu) 2. Smarty Address Verification 3. Show tools 4. Validate only 5. OK/Cancel

Pros: Fast, accurate address lookup integrated with our product, without introducing a "new and different" UI look and feel.

Cons: No complaints about the product. The name of the product is a little quirky, but it is certainly memorable.

Pros: We added Smarty to the foundations register and donation forms around a year ago and it has greatly streamlined the form completion process. When reviewing the data on the numbers using the Smarty tool month over month, it's amazing to see! Very useful for us and our constituents

Cons: I don't have anything I dislike about this tool! A must on our forms. The tier we chose has given us plenty of room to grow our forms.

Pros: Smarty is very easy to use and performs extremely well. It does one things and does it very well. I have had no issues at all.

Cons: I don't think there is much to dislike about Smarty. I honestly can't think of a con. The price maybe if you are on a budget and need to verify a lot of addresses but honestly I think the price is very reasonable, so even that doesn't seem like much of a con.
