The Top 3 Online ESA Letter Sites Reviewed
Hi everyone, I’m Chloe, and this is my best friend and emotional support animal, Lucky!
Lucky means the world to me, and when I had to move, I wanted to make sure that a no-pets policy wouldn’t separate me from my BFF. Lucky helped with my depression and anxiety for years as my unofficial support animal. I wanted to make that relationship official and have Lucky be my legal ESA by getting an ESA letter.
At first, I was overwhelmed by the number of options offering ESA letters online. If you’re reading this, you might be in the same boat. After spending weeks researching, I’m sharing everything I learned and my top picks.
Online ESA Letter Services I Picked and Tested
After all my research, ESA Doctors emerged as the clear winner for me and Lucky. Here’s what set them apart:
They’ve Been Around The Block
ESA Doctors has been in business since 2015, which gave me immediate confidence. They’ve helped over 100,000 clients, and when I dug into Reddit discussions and detailed reviews, I found overwhelmingly positive experiences. One person mentioned they’d been using ESA Doctors for three years across different states without any issues. Their BBB rating is a perfect A+, and their client reviews are immaculate.
They do Things the Right Way
Unlike some sites that approve you instantly (red flag!), ESA Doctors connected me with a real licensed therapist who took time to understand my situation. They put their license and contact information on the letter so that my landlord could verify it was from a real healthcare provider. An ESA letter is also worthless if it doesn’t actually work: ESA letters given by the therapists they work with have a 99% acceptance rate by landlords, which is exceptional and inspires confidence.
They Have Your Back
What really sealed the deal was their ongoing support. ESA Doctors will provide ongoing support and documentation as needed if your landlord gives you trouble. Their team is entirely U.S.-based (no bots or offshore agents!) and respond quickly. In addition, their site was an amazing resource for any ESA-related questions you could have, with hundreds of top-notch educational articles written by experts. They also have a major benefit if you have more than one pet: ESA Doctors doesn’t charge extra fees for multiple ESAs like their competitors do.

My Experience with ESA Doctors
I was initially nervous about the whole online ESA letter thing — it felt like it could be a scam. My research led me to believe ESA Doctors would be the best online option. I was still anxious, but ESA Doctors put my fears to rest immediately. The support team at ESA Doctors were kind and patiently answered all of my questions before I decided to go with them. The intake process was straightforward, and within a day, a licensed therapist reached out to me to schedule a consultation.
I got an ESA letter that looked like the real deal with the therapist’s signature and licensing information. I was able to submit my ESA letter to my landlord with confidence, and it got accepted without any problems!
#2 Runner Up:
CertaPet — Professional and Reliable
4.7/5
Highlights
- Long track record in the industry
- BBB accredited with an A+ rating
- Licensed professionals in all states
- Good customer service response times
- Great understanding of ESA guidelines and rules
What Could Be Better
- Hard to figure out pricing
- Extra $99 fee for more than one ESA
- Website navigation and the intake process could be clearer
- Some users report communication issues with therapists
- Mixed reviews about follow-up support
Why CertaPet is My Runner-Up
With generally positive ratings and a long track record, CertaPet is a solid choice. Ultimately, they were not my top choice because I found it hard to figure out information about pricing and process on their website. Some reviews also reported mixed feelings about their interactions with the therapists and customer support. They also charge a hefty extra fee if you want an additional emotional support animal even though the consultation is with the same therapist. I also got the impression that they were a larger company with a less personal feel.
#3 Third Place:
ESA Letters — Quick and Straightforward
4.6/5
Highlights
- Relatively fast turnaround time
- Simple, user-friendly process
- Well-designed and easy-to-navigate site
- Affordable and transparent pricing (and no fees for extra ESAs)
- No frills service to get an ESA letter
- Educated about the latest rules
- Responsive customer support
What Could Be Better
- Track record and history are not as long as the top picks
- A bit too bare bones, I would have liked some more information on their site
Just the Essentials
I really liked their website and intake process. It was intuitive and easy to navigate. The customer support team was responsive and friendly. They deliver on exactly what they promise: an ESA letter from a licensed healthcare professional. I couldn’t find any negative information about them, but they also didn’t have as much of a history as my top choices.
#Honorable Mention:
Pettable
4.4/5
Highlights
- Modern, easy-to-use website
- Good marketing and brand presence
- Generally positive, but some polarizing reviews
What Could Be Better
- Mixed online reviews, especially by Redditors
- Reports of certain landlords screening for Pettable-branded letters
- Extra fees if you have more than 2 ESAs
- Slightly higher number of BBB complaints
- Client reports of letters being rejected
Why Pettable Fell Short
While Pettable has a great website and is heavily marketed, I found concerning discussions on Reddit. Several users on Reddit reported that their ESA letters didn’t work. A deep dive into their reviews also shows some users reporting negative experiences with customer service. While many users did have positive impressions, ultimately, I didn’t feel as comfortable with this service based on users that consistently reported similar problems. Some people also report receiving unwanted spam.
Services That Might be Okay but Not The Best
Wellness Wag
Wellness Wag promises a quick turnaround and has some positive reviews, but some red flags emerged during my research. They have a smaller number of reviews and lower ratings than my top picks. They offer a really quick 24-hour turnaround, which can be helpful to some people, but also makes me wonder if a complete evaluation can actually be done in that time. They also charge extra fees if you have more than one emotional support animal. There have been Reddit reports of some people feeling that their ESA evaluation wasn’t completed properly. They’ve specifically been flagged by a Florida-based ESA advocate as well as being questionable.
Support Pets
On first impression, they appeared to have solid ratings, but digging into the reviews revealed a different story, especially regarding surprise fees. They have an A- rating on BBB (versus the A+ rating of my top picks) and a troubling number of complaints. Many clients report having difficulty with their support team, and there are also discussions on Reddit about poor experiences. Their advertising is also a bit misleading — it gives the impression that emotional support animals can come with you anywhere (they can’t). Their service may work for you, but given the other options, I can’t recommend them.
Proceed with Caution!
EasyPetsYes
This is another company that, on first impression, seems fine based on reviews but reveals problems upon deeper digging. Several Reddit posts have questioned whether this is a legitimate service. I’m also wary about the extremely low price and advertised turnaround time of just “minutes”. You really shouldn’t be able to get an ESA letter that fast. A Florida-based ESA activist on Reddit has noted that all of this doesn’t add up. I also couldn’t find any information about whether they are BBB-accredited. Proceed at your own risk.
United Service Dog
This company had several red flags for me. One was their poor customer ratings. They have an extremely low 2.6 rating on Trustpilot. Next, I was troubled by their pricing structure. They offer expensive and unnecessary add-ons like registrations and certifications, which makes me wonder if they have the customer’s best interests in mind. I also found the website to be difficult to navigate and a bit unprofessional in feel. They are also not BBB accredited.
What to Watch out for in an ESA Company
When researching ESA letter services, I learned to look for specific legitimacy markers. Legitimate companies must provide consultation with a licensed mental health professional in your state, include verifiable license numbers you can check on state boards, and offer transparent pricing with real customer support. A proper letter should have professional letterhead, the therapist’s full contact info and license number, and explicit reference to the Fair Housing Act – not some decorative certificate.
I spent hours avoiding major red flags like:
- “Instant approval” promises or letters delivered in minutes
- Claims about airline or public access rights (which ended in 2021)
- Hidden fees and prices under $100 since real therapists charge for their time
- Generic certificates instead of proper legal documentation
My research process involved reading detailed Reddit reviews for specific user experiences rather than generic five-star ratings, then verifying therapist credentials through state licensing boards. I also searched company names plus terms like “lawsuit,” “BBB complaints,” and “fraud investigation” to uncover any issues.
You might be tempted by cheap options, but they often cost double when you have to get a real letter after the fake one gets rejected. The peace of mind from doing proper research was worth the investment.
