Easy to get started

So, I needed some email stuff for my AI project, you know, like to send out transactional emails for agents. Mails.ai popped up, and honestly, it was pretty easy to get going. The website wasn't confusing, which is always a plus. I just picked what I needed, got my developer API keys, and plugged them in. It's been working fine ever since. Felt pretty good about the whole process.

Consistently good service

I've used Mails.ai for a few projects now, mostly for the email API for AI agents. This time I got more per-agent email addresses and the setup was just as smooth as before. They're reliable, and the prompt injection scanning works great. It's why I keep coming back for new projects.

Decent value for annual plan

As a first-time user, I was looking for the best deal. I opted for the annual billing to get the 20% off. It made the cost for the email API for AI agents much more manageable for our startup budget. The features like prompt injection scanning and email identity management are crucial for us. So far, the value for money seems fair given the specialized service they provide. It was a worthwhile purchase.

Smooth setup, good support

I was setting up automated email infrastructure for a new AI agent project and went with Mails.ai. Ordering the developer API keys was straightforward on their site. Delivery was instant, obviously, since it's an API service. I had a small question about inbound email parsing configuration, and their support got back to me within a few hours with a clear answer. The per-agent reputation management seems to be working well, emails aren't getting flagged. It's a solid platform for anyone needing specialized email for AI.

Thinking about switching from SendGrid to Mails.ai. Anyone done that? How does it compare in terms of features for AI agents?

J Julia 2 months ago

Mails.ai is definitely more specialized for AI agents. SendGrid is a general email API, so Mails.ai has features like per-agent emails and prompt injection scanning that SendGrid just doesn't offer.

I moved from Mailgun and the difference for AI stuff is night and day. Mails.ai really focuses on the unique needs of LLMs and agent communication, whereas Mailgun felt like I was duct-taping a solution together.

Is Mails.ai actually good at stopping prompt injection? That's my main concern with AI agents.

K Kevin E. 1 month ago

That's one of their main selling points, yeah. They have built-in scanning for it, which is way better than trying to roll your own solution.

J Julia 1 month ago

They specifically mention prompt injection scanning as a feature. Haven't had any issues personally, seems to work well enough from my experience.

Are there any startup discounts for Mails.ai? Just launching and every bit helps.

A Andre R. 2 months ago

Yeah, I heard they do offer something for startups. You might need to reach out or check their specific programs during sign-up.

E Emma 2 months ago

I think they have a startup program or some kind of credit for new businesses. Worth looking into their 'developer credit' options too, might be similar.

Hey, wondering if anyone knows about free trials for mails.ai? wanna test it out before committing.

M Megan 2 months ago

Yeah, they definitely have a free trial. I think you just sign up and it's automatically there for a bit to check out the API.

Can confirm, got some developer credits when I signed up. Let me play around with it for a while which was super helpful.

How easy is it to integrate the Mails.ai API? Not super dev-savvy, so hoping it's straightforward.

T Tom 2 months ago

It's pretty standard API stuff. If you've used other email APIs before, it's very similar. They have good docs.

D Dana 2 months ago

I found it quite easy, honestly. Their documentation is clear, and for basic stuff, you can get going quickly. For more complex setups, might need a bit more digging but overall solid.

Does anyone know if there are discounts for annual plans? Trying to figure out if it's worth going for a longer commitment.

S Steve 2 months ago

Yep, they do! I got a pretty solid discount for paying annually. I think it was around 20% off compared to monthly.

C Cleo 1 month ago

Most SaaS companies do annual discounts, and Mails.ai is no exception. Definitely check for that option when you're setting up your account, it's usually applied directly.

How's the pricing structured for Mails.ai? Is it like per email or per agent or what?

R Rachel 2 months ago

From what I remember, it's more about the number of agents and the volume you're pushing. Not a simple per-email charge like some others.

P Paula 2 months ago

They have different tiers, I think it scales with your usage, especially for the per-agent email addresses. Better check their pricing page for specifics, but it's not a flat rate.

What's the deal with their reputation management? Is it actually useful or just marketing speak?

S Sarah Nguyen 2 months ago

It's legit. Helps keep your AI's emails from landing in spam, which is a huge deal when you're sending out a lot.

6

T Tara Whitfield 2 months ago

From what I understand, it monitors and helps maintain the sending reputation for your agents' emails. It's pretty critical for deliverability, especially compared to just using a regular email service that doesn't care about AI-specific sending patterns.
