Frequently asked questions about mailings

  • Can I send a mailing to my own chats and contacts?

    Yes. After an account is connected, the service syncs its chats and contacts, and when launching a mailing you can pick them as recipients. The Only chats with conversations filter is on by default, so the mailing does not go to random dialogues.

    Contacts can also be saved to segments and used in the next mailings. Chat sync and segments are available on paid plans.

  • How do I launch a mailing in a messenger?

    When launching a mailing for the first time, choose Connect a new account. A QR code will appear, which you need to scan in the messenger's mobile app.

    After the first mailing from the new account is completed, the account stays connected to the service, and no QR code scanning is needed to launch the next mailings.

  • How many accounts can be connected to the service?

    The number of connected accounts depends on your plan:

    • Free Basic plan — 1 account.
    • Light plan — 1 account.
    • Professional plan — up to 50 accounts.
  • Can an account be blocked?

    It can: when an account starts behaving like a spammer, the messenger temporarily restricts sending. The most common causes are:

    • Auto-strategy is disabled and the speed is pushed up manually;
    • The message does not invite a dialogue;
    • Many complaints from recipients;
    • A link sent to a stranger in the very first message;
    • A promo image in the very first message;
    • A purchased contact list of people who do not know you.

    WSENDER lowers this risk automatically: the auto-strategy warms up the account, increases the speed gradually and slows down at the first sign of trouble, while AI moderation checks the message text before launch.

Feedback from our users

  • Bakhtiyar

    Real estate

    I've been using the mailing service for a couple of months and I'm completely satisfied. What I especially liked is that you can set up mailings for WhatsApp and Telegram from a single account — it saves a lot of time. The interface is convenient; it took me literally 10 minutes to figure it out. Support responds quickly and to the point. I definitely recommend it to anyone who wants to automate communication with customers!

  • Valentin

    Retail

    I was looking for a convenient tool for mailings in several messengers at once — and finally found it. The service let me bring WhatsApp and Telegram together in a single system. Template setup and audience segmentation made communication with customers much more effective. The reporting is transparent, everything is tracked in a couple of clicks. Many thanks to the team — you really made my work easier!

  • Lena

    Marketing

    I started using the service with caution — I thought the settings would be hard to figure out. But everything turned out to be surprisingly simple: an intuitive interface, detailed hints and an excellent support team. When I had questions about setting up mailings for Telegram, the operator replied within 5 minutes and helped solve the problem. Now I launch mailings in WhatsApp and Telegram in a couple of clicks. Very happy with my choice!

  • Katya

    Food service

    The service lived up to expectations: mailings work stably, there were no errors. I liked that there is integration with different messengers. There are small things that could be improved, but overall everything is great.

    Simply a lifesaver for small business! I used to spend hours manually sending messages to customers in different messengers. Now everything is done automatically — set it up once and forget about it. It helps a lot! Thanks for such a great service!

    Education

    Huge thanks to the service. I work in offline education, and thanks to the service my sales grew several times over. Special thanks to the support department and the service's marketers, who advised on how to compose messages properly and make the mailing effective.
