AI capabilities of the service

  1. Semantic AI evaluation

    The AI evaluates the text before launch: advertising tone, pressure and urgency, template-like wording, lack of motivation to reply.

  2. Precise checks

    The system instantly finds links and contacts, excessive CAPS, overly long text, a missing greeting and prohibited topics.

  3. One-click fix

    The AI rewrites the problem spot itself: removes links, softens advertising, adds a greeting, shortens the text. You accept the result, edit manually or ignore the remark.

  4. Pause until your decision

    A mailing with serious remarks does not reach recipients: it is paused, and you receive the list of problems and a Telegram notification. Once fixed — it starts by itself.

  5. Text uniqueness

    An identical message for everyone is almost guaranteed complaints. The system checks randomization, and the AI creates text variants for you.

  6. Message creation

    The AI marketer writes a ready-made mailing text from a short brief — engaging, spam-free and with a lower blocking risk.

Frequently asked questions about the service

  • How do I make a mailing in WhatsApp?

    The list of all connected accounts is in the My accounts section.

  • How do I make a mailing in Telegram?

    The list of all connected accounts is in the My accounts section.

  • Can I address recipients by name in the mailing text?

    Yes. You can put any personal data into the message text — the customer's name, order number and so on. To do this, upload the recipient contact base from an Excel file that contains the corresponding personal data alongside the phone numbers.

    Read more about personalized messages in the article.

  • Can I see who received the message?

    Yes. You can enable performance analytics for a mailing: it analyzes delivery statuses, reads and replies to the mailing messages and builds a report.

  • How long should a text message be?

    Technically, a text message can be up to 2,000 characters, and a caption for an image, video or file up to 700 characters. For the best reply conversion we do not recommend making messages too long or too promotional. The optimal message length is 500 characters.

  • What size and proportions should mailing images have?

    The image size must not exceed 10 megabytes.

    The optimal image proportions for messenger messages are:

    4:5, 1:1, 16:9

    With these proportions the picture is not cropped, so it does not have to be opened for a full view.

    Read more about image proportions in the article (in Russian).

  • 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.
