Guides for every part of WiseSender

Create your account

Sign up with your work email and a password of at least 8 characters. We email you a 6-digit code: enter it in the dashboard to confirm your address. Confirming unlocks your signup bonus and lets you send email.

1. Open wisesender.com/dashboard and choose Sign up.
2. Enter the code from the confirmation email in the bar at the top of the dashboard. The code works for 30 minutes; ask for a new one if it expires.
3. You now have your free signup credits, 20 free verification credits every day, and 100 test emails for sending.

Find your way around

Check one address

Go to Single verify, paste an address and press Verify. In a few seconds you see the result, a 0 to 100 score and the reason. One check uses one verification credit. If the mail server gives no clear answer, the result is Unknown and the credit comes back automatically.

Nobody receives anything: the check talks to the receiving mail server and stops before a message would be sent.

Clean a list

1. Open Bulk upload and drop a CSV or TXT file (up to 25 MB and 100,000 rows), or paste addresses.
2. WiseSender finds email addresses in any column and removes duplicates. You only pay for unique addresses, and you see the cost before you start.
3. Checking runs in the background. You can close the page; the list keeps going and shows up in Results when it is done.
4. Download the cleaned list as CSV or Excel: everything, or only the categories you choose, such as Safe only.

Results stay in your account until you delete them. Your last 1,000 single and API checks are kept too.

Read the results

The score sums it up: safe addresses score around 90 to 95, role 75, catch-all 55 and invalid 0. Possible typos such as gmial.com are capped at 35 and come with a suggested fix.

Power and quick mode

Power mode asks the receiving mail server whether the exact inbox exists. Use it before a campaign. Unknown results are refunded.

Quick mode checks syntax, the domain, its mail servers and throwaway providers in under a second, but can't confirm the inbox, so it never marks an address Safe. It suits signup forms where speed matters. Quick results are always charged.

Lists and signup forms

In Contacts & forms, create a list for each audience, for example Newsletter or Customers. Every list comes with a hosted signup form.

• Share the form link anywhere, or copy the embed code and paste it into your website.
• Import existing contacts from a CSV or TXT file. Only import people who agreed to hear from you.
• Add by API from your app or with the WordPress plugin, Zapier, Make or n8n. Add "verify": true to refuse typos and throwaway inboxes as they come in.

Double opt-in and welcome email

Turn on double opt-in for a list and new subscribers get an email with a confirm link. They only join the list after they click it, which keeps fake and mistyped addresses out.

A welcome email goes out as soon as someone subscribes, or confirms when double opt-in is on. Write it once in the list settings. It is sent from your connected mailbox.

Unsubscribes

Every campaign has an unsubscribe link and the one-click unsubscribe header that Gmail and Yahoo show next to the sender. When someone unsubscribes, they are marked in the list and added to your suppression list, so no later campaign reaches them, whichever list or file you send to.

Add your domain

Email sent through WiseSender goes out from your own domain, signed with your own DKIM key. Add the domain once:

1. Open Domains and add the domain you send from, for example acme.com.
2. Copy the DNS records shown (DKIM and the MAIL FROM records) into your DNS provider.
3. Wait a few minutes to a few hours, then press Check. The domain turns Verified when the records are found.
4. For campaigns, also publish a DMARC record if you don't have one yet. A simple start is a TXT record at _dmarc with v=DMARC1; p=none; rua=mailto:[email protected].

Templates

Design an email once in Templates with simple blocks (header, heading, text, image, button, divider, spacer and footer) or paste your own HTML. Preview it on desktop and mobile, then reuse it in any campaign or welcome email.

Send a campaign

1. Open Send email and choose Send with WiseSender.
2. Pick who gets it: a contact list (subscribed people only) or a verified list from Results, with Safe only, Safe and role, or all reachable addresses.
3. Choose the sender: a name, an address on your verified domain and an optional reply-to address.
4. Write the subject, pick a template or write the email, and turn open and click tracking on or off.
5. Send now or schedule it for later. You see the recipient count and the credits it will use before you confirm.

Each recipient uses one email credit, the same credits as transactional email. Addresses that unsubscribed or bounced before are skipped and not charged. Campaign results (sent, delivered, opened, clicked, bounced, unsubscribed) appear on the campaign as they come in, and you get an email when it finishes.

To send campaigns through WiseSender you need a confirmed account email, a verified domain with DMARC and at least one email credit pack. This keeps the shared sending reputation clean for everyone.

Send from your own mailbox

You can also send a campaign through your own Gmail, Outlook, Zoho or business mailbox. Add its SMTP details under Send email → Mail settings. Gmail, Yahoo and iCloud need an app password instead of your normal password: turn on 2-step verification, then create one in your account's security settings.

Mailbox sending is paced at about 30 emails a minute and up to 2,000 recipients per campaign, because providers limit how much one mailbox may send. For bigger lists, send with WiseSender.

Transactional email

Send login codes, receipts and alerts from your app in Transactional API:

• Agents are separate streams of mail, such as OTP, Invoices or Password reset. Each has its own sending keys and stats, so you can revoke one without touching the rest.
• Send with the REST API (docs) or through SMTP with any framework or plugin that can send email (SMTP settings).
• Templates keep the design in WiseSender: your app sends the template name and the values.
• Webhooks tell your app about deliveries, bounces, complaints, opens and clicks. Logs show every message and what happened to it.

Stay out of spam

• Verify lists before you send, and send campaigns to Safe addresses first.
• Only email people who asked to hear from you. Never send to bought or scraped lists.
• Set up DKIM and DMARC on your domain, and keep the from name and address the same between campaigns.
• Start small with a new domain and grow volume over a few weeks.
• Write like a person: a clear subject, a real reply-to address, and an obvious way to unsubscribe.

To protect everyone's delivery, sending pauses automatically when an account's bounces go above 5% or spam complaints above 0.3% over 7 days (after the first 100 emails). If that happens, clean the list and contact support to resume.

Credits and limits

We email you when your credits run low, so sending doesn't stop by surprise.

Payments and invoices

Buy credit packs in Credits & billing. There is no subscription: you pay once per pack. After payment the credits are added as soon as the payment provider confirms it, usually right away, and a receipt arrives by email.

Every paid order has an invoice you can open and print from Credits & billing → Payments. Questions about a charge? See the refund policy or contact billing.

Team access

Invite teammates under Transactional API → Team with one of three roles: Developer, Viewer or Admin. They log in with that email (or sign up with it) and pick your workspace from the Workspace menu.

Profile, privacy and deletion

• Change your name, company and password in Profile.
• Change your cookie choice any time with Cookie settings at the bottom of the website.
• Getting-started tips come by email in your first week. Each one has a link to stop them; account emails such as receipts still arrive.
• Delete your account in Profile. Your lists, contacts, results and keys are removed. We keep payment records only as long as the law requires. See the privacy policy.

Still stuck? Write to support. We reply within one business day.
