Best ESA Letter Online Services

With so many options available online, finding the right ESA letter service isn’t easy. To help you find the right one, I've researched and ranked the top services based on effectiveness (meaning will the ESA letter actually work), customer reviews, pricing, and overall reliability.

The Top Tier

#1 ESA Doctors

Why They're The Best

ESA Doctors has earned its spot at the top with over a decade of reliable service. They've built a strong reputation and loyal following with ratings of 4.9 out of 5 stars from Dogster, 4.9/5 stars from Shopper Approved and 4.8 out of 5 stars from Catster. Reader's Digest recommends ESA Doctors as a trusted service to obtain ESA letters, and reviewers note their 99% landlord acceptance rate.

What Makes Them Stand Out

• They hold an A+ BBB rating with verified customer reviews
• They connect you with licensed mental health professionals who conduct proper assessments - reviewers note that their partnerships with licensed professionals ensures legally valid letters
• U.S.-based support team and ongoing assistance if landlords push back
• Full refund if you don't qualify
• Transparent pricing with no extra charges for multiple ESAs
• As Dogster notes, "they offer so much support on their website" including state-specific ESA information

ESA Doctors is the obvious pick for anyone looking for a legitimate, federally-compliant ESA letter with strong customer support and a proven track record.

#2 CertaPet

Why They're Solid

CertaPet is a veteran-owned company with a Gold Star from the BBB. Cats.com ranks them as a top pick, noting they have "over 65,000 satisfied customers" and provide legitimate ESA letters through licensed professionals across all 50 states.

Strengths

• A+ BBB accreditation
• Licensed mental health professionals including psychologists, licensed professional counselors, and clinical social workers
• Good understanding of ESA guidelines and regulations
• Free screening before payment
• Simple 3-step approval process with consultations within 48 hours

Slight Concerns

• Additional hefty $99.99 fee for more than one emotional support animal
• Hard to figure out final pricing
• Website navigation could be clearer
• Mixed reviews about therapist communication
• Mixed reviews about follow-up support

#3 US Service Animals

A Decent Alternative

US Service Animals has a lot of reviews on Trustpilot from users who say their ESA letters worked. My Dog Is A Robot notes that they are "one of the top providers of both ESA and PSD letters".

Positives

• Straightforward process with professional staff
• Large number of reviews on third party sites
• Clear pricing

Drawbacks:

• Mixed reviews across platforms - 5 stars on Trustpilot but only 2.7 stars on Sitejabber
• Some customers report persistent phone calls even after opting out
• Registration services are unnecessary for legal ESA status, offering them can confuse clients

Honorable Mention

Pettable ⭐⭐⭐

Positives

• Easy to use website
• 24-hour turnaround option available
• Full money-back guarantee
• The Washington City Paper ranked them highly, noting their "competitive pricing and straightforward process"

Concerns:

• BBB complaints include billing issues, missed therapist appointments, and problems with receiving correct letters
• Reddit discussions report some landlords screening for and rejecting Pettable-branded letters
• Some customers report difficulty getting refunds despite the guarantee
• Extra fees for more than 2 ESAs

Services to Avoid

Wellness Wag

EasyPetsYes

Red Flags

• Limited verifiable customer reviews from independent sources
• Questions raised by ESA advocates about legitimacy
