So good for my app!

Mailboxlayer is amazing! I just integrated their Disposable Email Detection into my new app and it works perfectly. The API Documentation was super clear, and I had it up and running in no time. My bounce rates are already looking better. I'm definitely going to recommend this to my developer friends!

Worked great for my site

Needed to clean up my email list, so I got the SMTP Validation service. It was pretty easy to set up, just followed the docs. Everything went well, no big headaches. My only minor thing is I wish the dashboard looked a bit more modern.

Always reliable service

I've used Mailboxlayer for a couple of years now, mostly for the SMTP Validation and Disposable Email Detection. This latest purchase for an upgraded monthly subscription was smooth, just like all my previous ones. The API's consistent performance is why I keep coming back; it just works every time, which is crucial for my applications.

Good value for annual plan

I was looking for an affordable email verification API for my side project. The 20% off annual billing for the Real-time Email Verification API made a big difference. It felt like a solid investment compared to other options I checked, and the features are exactly what I needed without breaking my budget.

Mostly good, some docs could be clearer

The Real-time Email Verification API has been quite helpful for reducing bounce rates, and the pricing is fair. Delivery of the API access was instant, which was great. However, I found some parts of the API Documentation a bit dense, especially when trying to understand the nuances of Catch-all Detection. It took a bit more trial and error than I expected to get it fully integrated. Overall, a solid service, but a clearer examples section for advanced features would be a big plus.

Reliable service, as always

I've used Mailboxlayer for a few projects now, mostly for the Real-time Email Verification API. This latest purchase for an Annual Subscription Plan was just as smooth as previous ones. The API consistently performs well, though I did notice a slight delay in the dashboard updating my new usage limits this time around. Still, it's my go-to for email validation.

Solid API, good support

I purchased the Monthly Subscription Plan for my small business to use their Bulk Email Verification. The ordering process was straightforward on their site, and I got access to the API key immediately. Delivery, in terms of API access, was instant. I had a small question about integrating the JSON API with my specific setup, and their technical support responded within a few hours with a helpful link. The quality of the verification is high, catching most of the bad emails I tested. The only minor point is that the developer sandbox could offer a few more advanced testing scenarios.

API works as promised

Signed up for the monthly subscription. Email verification API was easy to integrate into my system. Documentation was clear. Had a small issue with rate limiting at first, but support quickly clarified.

Hey guys, thinking about signing up for Mailboxlayer. How's the accuracy for catching all those fake emails? Don't want to pay for something that lets a bunch through.

A Andrew Garcia 4 weeks ago
From my experience, it's pretty solid. I've been using it for a few months and it flags most of the garbage emails I get from forms.

S Sam N. 4 weeks ago
Yeah, I've found it to be really accurate. Their disposable email detection is especially good, which saves a ton of headaches.

hey, trying to figure out if mailboxlayer is any good compared to, say, neverbounce? seen both advertised but wanna know if there's a big difference in accuracy or speed for email validation.

D Danielle 4 weeks ago
I used NeverBounce for a bit and it was fine, but Mailboxlayer's free tier was a big draw. For basic checks, I haven't noticed a huge difference, but my volume isn't crazy high.

K Katie Lewis 4 weeks ago
From what I hear, Mailboxlayer is pretty solid for catching disposable emails and general syntax errors. Some people say NeverBounce might have an edge on really obscure catch-all domains, but for most businesses, Mailboxlayer holds its own. Plus, the dev sandbox is super handy for testing.

Are there ever any promo codes for new users? I'm thinking of signing up for a paid plan but trying to save a few bucks if possible.

A Andrew 3 weeks ago
They do sometimes. I got one through a dev platform I use, so keep an eye out there. Or maybe around Black Friday? I think they have sales then.

E Elizabeth Smith 3 weeks ago
Mostly it's the free tier they push. But yeah, sometimes new user stuff pops up, especially if you get referred or through specific tech partnerships. Don't always count on it though, the annual discount is probably your best bet for consistent savings.

I'm thinking about going with an annual plan to save some money. Is it a significant discount compared to paying monthly?

A Alex White 3 weeks ago
Oh yeah, definitely. I think it's like 15-20% off if you switch to annual. Worth it if you plan on using it for a while.

B Brandon Allen 3 weeks ago
Big difference! I switched to annual last year and it saved me a decent chunk of change. Plus, one less thing to worry about each month.

Trying to decide between Mailboxlayer and ZeroBounce. Has anyone used both and can tell me which one they prefer for general email verification?

A Amanda N. 1 month ago
I've only used Mailboxlayer, but it's been great for me. Super easy to integrate and the free tier is awesome for testing.

ZeroBounce is good too, but I found Mailboxlayer's pricing a bit more straightforward, especially if you're not doing super high volume. Plus, the dev sandbox on Mailboxlayer is really handy.

Quick question on payment methods. Can I use PayPal, or is it just credit cards for Mailboxlayer?

B Ben Martin 1 month ago
Pretty sure it's just credit cards. I paid with my Visa last time.

L Lisa M. 1 month ago
I think they only do major credit cards. Didn't see a PayPal option when I signed up for my annual plan.

Anyone know if Mailboxlayer ever does special deals? Looking to sign up but waiting if there's like a Black Friday sale or something coming up.

M Matt Smith 1 month ago
They do sometimes! I got a promo code once when I was checking out through a dev platform. Keep an eye out around holidays like Black Friday or New Year's.

C Chris T. 1 month ago
Yeah, I've seen them run promotions for first-time users. Also, if you're thinking annual, that's usually a pretty good discount on its own.

If I sign up for a paid plan but decide it's not for me, can I get a refund or am I just stuck with it?

J Jeff Williams 1 month ago
Hmm, I don't think they do refunds. You can cancel your subscription at any time, but I'm pretty sure once you've paid for the month/year, that's it.

R Rachel A. 1 month ago
Yeah, I remember reading somewhere they don't really do refunds. Best to use the free tier a lot first to make sure it's what you need before committing to a paid plan.
