Most mainstream platforms' policies rule peptide brands out. These are the options that are actually open to you, with what each one publishes about the category. We run one of them, and we've said which.

Policies and pricing pages checked November 1, 2026

Five store-triggered flows, campaigns, segments, forms, SMS with carrier registration, revenue split into confirmed and likely.
Your own sending domain, warmed up for you; deliverability gates on every send.

3. Amino Engine

Self-serve email, SMS and ads software. Best for brands that want to run their own platform and want ads tooling in the same place.

Its policy says the platform was built for peptide and research-use brands, with rules on claims and disclaimers.
Public pricing with a low entry tier, a WooCommerce plugin listed on WordPress.org, promotional SMS behind a strict editor.

Amino Engine acceptable use policy

4. Sendlane

Ecommerce email and SMS software. Best for brands working with an agency that already runs it and has a written yes for their category.

What it has

A mature ecommerce platform with flows, segments and SMS.
Some peptide-focused agencies use it for clients.

Watch for

Its terms say businesses offering pharmaceutical products cannot use the service. Peptides aren't named. Get your category confirmed in writing before moving a list.

Sendlane terms

5. Self-hosted (Listmonk, Mautic or Sendy, plus a sending relay)

Software you install and run. Best for technical teams that want to own every piece and can run deliverability themselves.

What it has

Nobody can review your account out of existence: you own the app and the list.
Low software cost.

Watch for

The sending relay (Amazon SES or an SMTP provider) has its own acceptable use policy and can still suspend you.
Warm-up, bounce handling, consent records, attribution and compliance footers are all yours to build and watch.
Store-triggered flows take real integration work.

Listmonk

Usually not on the list, and why

KlaviyoIts policy doesn't allow prescription medications or pharmaceutical products, the rule peptide stores fall under.
OmnisendIts policy bans pharmaceutical products and prescription medications and says that includes drugs for research purposes.
BrevoIts policy bans peptide-based products by name, including ones labeled research use only.
MailchimpLists pharmaceutical products among businesses it may not allow; supplements get additional scrutiny.
ActiveCampaignBans messages about drugs and any product that claims to treat or prevent a disease.

Every line above is paraphrased from the platform's own policy, linked in our guide to which email platforms allow peptide brands.

How to choose

Ask for your exact catalog in writing. A signup approval isn't a policy review.
Decide whether you want to operate the platform or have it run for you. That's the real split between the options above.
Insist on your own sending subdomain, so the reputation you build moves with you.
Check how revenue is counted. Last-touch credit makes every email look like it works.
Export on a schedule, wherever you land.

Questions

What is the best email marketing platform for peptide brands?

One whose published policy names your category as allowed, that sends from your own domain and lets you export anytime. TellySend is built for peptide brands and run for you by a team; OneMoreSend and Amino Engine are self-serve platforms whose policies allow peptides for email; Sendlane is used by some peptide agencies but its terms bar pharmaceutical products; self-hosting works if you can run deliverability yourself.

Can I use Klaviyo for a peptide brand?

Klaviyo's acceptable use policy doesn't allow prescription medications or pharmaceutical products, and that is the rule peptide stores fall under. Read the policy and ask in writing before you build a list there.

Which platforms allow SMS for peptide brands?

It depends on US carrier registration more than on the platform. OneMoreSend limits peptide SMS to transactional texts; Amino Engine allows promotional texts behind a strict editor; TellySend registers each brand and tells you what it qualifies for before anything sends.

What should I check before moving my list?

Ask the platform in writing whether it accepts your exact products. Read every policy it points to. Send from your own subdomain so your reputation moves with you. Export your list on a schedule.
