Short answer
Moosend publishes its pricing, security statements and sender policies on its own site. Its pricing page shows a 30-day free trial with no credit card required and says it has 100,000+ customers; that customer figure is the company's own claim, not an independently verified number. [2]
The useful question for a small sender is what checks you will face and what protections Moosend documents. The answers below come from Moosend's Trust Center and help center, read on October 30, 2026. This page does not aggregate user reviews.
Who owns Moosend
Moosend's site carries the statement "Moosend is now a Constant Contact company," linking to Constant Contact's website. It appears on the Trust Center and other Moosend pages. [1]
The pages we read do not give a date for the change or link to an announcement. If ownership matters to your contract, for example for a data processing agreement, ask Moosend support which legal entity you will contract with before you sign.
What Moosend publishes about security and hosting
The Trust Center makes specific statements you can hold the company to. It lists ISO 27001, AWS, SSL, M3AAWG and the Certified Senders Alliance among its badges. It describes AWS data centers as certified against ISO 27001 and SOC 2, which is a statement about AWS infrastructure. [1]
The Certified Senders Alliance participant page for Moosend Ltd quotes Moosend's Senior Deliverability Manager on using CSA's monitoring tool. That page does not itself state a certification status or date, so treat the badge as something to confirm with CSA if it matters to you. [7]
| Claim on the Trust Center | What it says | What to ask for if it matters |
|---|---|---|
| Data location | Contact data is hosted in the EU through a partnership with AWS [1] | A data processing agreement naming the hosting region |
| Encryption | All data, including databases and in transit, is encrypted; encrypted backups are kept off-site [1] | Security documentation for your vendor review |
| Infrastructure certifications | AWS data centers are certified against ISO 27001 and SOC 2 [1] | Whether Moosend holds its own ISO 27001 certificate, and its scope |
| Industry groups | M3AAWG and Certified Senders Alliance badges listed [1] | Current membership or certification status from those bodies [7] |
The checks you will meet as a sender
Moosend verifies each sender address before you can use it. You add the sender under More, Settings, Senders, set up SPF and DKIM TXT records, and click an activation link sent to that address. A sender is rejected if it uses a free webmail address such as Gmail, Hotmail, Outlook or Yahoo, if no website is found for the sender's domain, or if the website, domain or address reputation is below Moosend's threshold. Prefixes such as admin, maildaemon, postmaster and no-reply are not allowed. [3]
After you send, Moosend watches bounce and complaint rates. If you exceed its thresholds, it blocks your account from sending campaigns and emails you, copying its Deliverability team. The team reviews blocked accounts Monday to Friday, 6:00 to 14:00 UTC. While blocked, the account stays active and you can use other features, but you cannot send campaigns. Moosend says blocks protect other customers' delivery and give you time to clean your list. [4]
- Use a sending address on a domain you own, with a live website.
- Publish SPF and DKIM before your first campaign.
- Import only contacts who opted in; Moosend says a block gives you time to clean your list and investigate your subscription sources. [4]
Consent tools and GDPR
Moosend's GDPR guidance says you can only send marketing email with active, specific consent, and that existing and new subscribers should go through double opt-in. Each list offers single opt-in, soft double opt-in (a confirmation email is sent but unconfirmed members stay on the list), or strong double opt-in (only verified subscribers receive mail). [5]
Strong double opt-in has a billing side effect worth knowing: Moosend says only verified subscribers count toward your bill, with unverified contacts excluded. For existing subscribers, Moosend suggests segmenting them and sending a campaign asking them to confirm through double opt-in. [5]
What happens to your data when you leave
Moosend says you must export any data you need before asking for deactivation, which you request by emailing [email protected]. Accounts not logged into for 300 days or more are deactivated for dormancy. After deactivation you have 30 days to reactivate, after which the account and any archived data are permanently deleted. Moosend adds that to reactivate and access your data you will have to purchase a new plan. [6]
That is a clear, documented retention window. Note the 300-day dormancy rule if you only send seasonally.
What this means for a small sender
For a small business with an opted-in list and its own domain, Moosend's published policies come down to a few specific friction points: no free-webmail senders, SPF and DKIM records before the first campaign, and a sending block, reviewed in business hours, if a campaign exceeds its bounce or complaint thresholds. [3] [4]
- Start the 30-day trial with no card and verify a sender on your own domain first. [2] [3]
- Turn on double opt-in for new signups and decide how to reconfirm older contacts. [5]
- Send a small first campaign to your most recent, engaged contacts before the full list. [4]
- If you need a DPA or certificates for a vendor review, request them in writing before you migrate.
- Diary a login at least every few months so the 300-day dormancy rule never applies. [6]
Questions before you decide
Who owns Moosend?
Moosend's own pages, including its Trust Center, carry the line "Moosend is now a Constant Contact company" and link to Constant Contact's website. Those pages do not give the date of the change.
Where does Moosend store my contact data?
The Trust Center says contact data is hosted in the EU through Amazon Web Services, that all data including databases and data in transit is encrypted, and that encrypted backups are stored off-site.
Why would Moosend block my account?
Moosend says it automatically blocks campaign sending when an account exceeds its bounce or complaint thresholds, then emails you. Its Deliverability team reviews blocked accounts Monday to Friday, 6:00 to 14:00 UTC. You can still use other features while blocked.
Can I send from a Gmail address in Moosend?
No. Moosend's help center says a sender is rejected if it uses a free webmail address such as Gmail, Hotmail, Outlook or Yahoo, if no website is found for the sender domain, or if reputation is below its threshold.
