Rate limit for topic email

Hey, I noticed today that I hit a rate limit on resend while sending out a weekly email that I trigger using a topic.
Is it possible somehow to add a delay so that not all email is sent at the same time?

@christian to make sure we undertand this, the issue is rate limit on resend API? are you looking for a solution for that? (debounce/throttle, fallback provider, retry)?

I use a topic for sending out a weekly e-mail, I got this response from resend for most of the emails

 
"Too many requests. You can only make 2 requests per second. See rate limit response headers for more information. Or contact support to increase rate limit."

I guess what I'm asking for is if I can add some kind of delay so that not all e-mails are sent at the same time for the topic, perhaps i could do this by adding a random delay in my workflow?

export const topRecipesWorkflow = workflow(
  TriggerEvents.TopWeekly,
  async ({ step, payload, subscriber }) => {
    const recipes = JSON.parse(payload.recipes ?? "[]");
    const userId = subscriber.subscriberId ?? "";
    const userFirstName = subscriber.firstName ?? "";

    await step.email("weekly-top-recipes", async () => {
      const emailBody = await renderEmail(recipes, userId, userFirstName);
      return {
        subject: "Top recipes last week",
        body: emailBody,
      };
    });
  },
  {
    payloadSchema: topWeeklyPayloadSchema,
  },
);

export const topRecipesWorkflow = workflow(
  TriggerEvents.TopWeekly,
  async ({ step, payload, subscriber }) => {
    const recipes = JSON.parse(payload.recipes ?? "[]");
    const userId = subscriber.subscriberId ?? "";
    const userFirstName = subscriber.firstName ?? "";

    await step.email("weekly-top-recipes", async () => {
      const emailBody = await renderEmail(recipes, userId, userFirstName);
      return {
        subject: "Top recipes last week",
        body: emailBody,
      };
    });
  },
  {
    payloadSchema: topWeeklyPayloadSchema,
  },
);

@christian that would be a simple and effective slution, I am also adding this to our product feedback under the category of throttling. @Dima Grossman @Pawan Jain maybe we can document a solution like that in the docs?
