## Problem

My emails take a long time to send.

## Cause

- The domain or IP address is new. For new IP addresses, Transactional Email progressively grants more email volume to ensure good domain reputation. For more information, see [Understanding your reputation score with TEM](/transactional-email/reference-content/understanding-tem-reputation-score/) and [Protecting domain reputation](/transactional-email/reference-content/protecting-your-domain-reputation/).
- If the domain is not new, the other possible causes are:
    - Unusual email sending volume compared to your history. In this case the sending rate will be adjusted automatically.
    - The email has been [greylisted](/transactional-email/concepts/#flags) by the recipient.
    - The shared IP is under pressure. 

## Solution 

- Send your emails progressively (100 emails/day) and slowly ramp up your volume over a period of weeks or months until you reach the desired volume.
- Subscribe to **Scale plan** and use a dedicated IP if you regularly send large volumes (> 100 000 emails/month).
- For critical needs, [contact our Support team](https://console.scaleway.com/support/tickets/create) to adjust the rate limit.
- Use [webhooks](/transactional-email/how-to/create-webhooks/) to delete emails that have [soft bounced](/transactional-email/concepts/#soft-bounce) and [hard bounced](/transactional-email/concepts/#hard-bounce).
